Influences of Process Parameters on Residual Stress and Tensile Performance of Riveted Joints2026-01-0183To be published on 04/07/2026
The mechanical integrity and performance of riveted joints critically influence the reliability and safety of automotive structures. To investigate the effect of residual stress on the tensile behavior of riveted joints, this study firstly established a finite element model of the riveting process using Abaqus software. The model was validated using the thick-walled cylinder theory, and the distribution of residual stress around the rivet hole was subsequently analyzed. Orthogonal experiments were subsequently conducted to examine the influence of key process parameters including rivet spacing, hole diameter, and upset head height on tensile performance, yielding simulation results for both radial residual stress and maximum tensile load. Based on the finite element analysis results, XGBoost and Kriging surrogate models were established using four key parameters as input variables, namely rivet spacing, hole diameter, upset head height, and arrangement pattern, with radial residual

Optimizing joint efficiency in stainless steel-aluminum alloy FSW joints through advanced parameter control2026-01-0228To be published on 04/07/2026
The present work investigates the friction stir welding (FSW) of dissimilar materials, specifically stainless steel 304 and aluminum alloy AA2024-T3, to analyze their tensile strength behavior. The significant challenges inherent in joining these materials, stemming from their vastly divergent thermal and mechanical properties, are addressed through a structured experimental and statistical methodology. The L18 Taguchi mixed orthogonal array was employed to systematically evaluate the influence of three critical process parameters: tool rotational speed, welding speed, and tool pin offset. Eighteen experimental trials were conducted using a butt joint configuration. The analysis identified tool rotational speed as the most influential parameter affecting the joint integrity. A combination of 450 rpm rotational speed, 20 mm/min welding speed, and a 1.5 mm pin offset toward the aluminum side yielded the optimum results, achieving a peak ultimate tensile strength (UTS) of 344.7 MPa and a

Predicting Tensile Properties of Cast Stainless Steels via Machine Learning2026-01-0237To be published on 04/07/2026
In the category of cast stainless steels, there are several variants per different level of addition of chromium (Cr), vanadium (V) along with some minor elements, such as molybdenum (Mo), niobium (Nb), tungsten (W) to meet the requirement of corrosion and oxidation resistance. However, the influence of chemical composition variations on the mechanical properties of cast SS continues to lack a clear understanding. In the present study, via machine learning (ML), the effects of each element on the tensile properties of the cast stainless steel are studied. The ML model is then used to predict how variations in elements affect tensile behavior, with the predictions validated through physical testing.

Machine Learning Modeling for Compressive Property Prediction of Foams2026-01-0512To be published on 04/07/2026
Foam material models for automotive structural analysis typically require tensile and compressive data at multiple strain rates. The testing is costly and may require a long time to complete. For many applications, foams of similar chemistry are used and the foam structural responses, such as stiffness and compression force deflection, are controlled by the foam density. In such cases, Machine Learning (ML) lends itself as an ideal tool to detect the trends in material response based on density and strain rate. In this paper, five microcellular polyurethane (PU) foams of different densities were tested at four strain rates ranging from 0.01/s to 100/s. A ML model capable of predicting compressive stress-strain response for a range of densities was developed. The model demonstrated good prediction capability for intermediate strain rates at all foam densities and in extrapolating stress-strain curves at higher densities at all strain rates. The strain rate trends for a density outside

Development of an Advanced Tensile Testing Method for HDPE Composites in High Draw Molded Hollow Circular Regions: Effects of Sample Preparation, Asymmetry, Thermal Conditions, Pull Speed, and Fixture Parameters.2026-01-0204To be published on 04/07/2026
High-density polyethylene (HDPE) composites, particularly in high draw molded hollow circular configurations, present unique challenges in evaluating mechanical performance under tensile stress due to anisotropic deformation, geometric asymmetry, and localized thermal gradients. This study introduces an advanced tensile testing methodology designed specifically to assess such regions with greater precision and reproducibility. The method incorporates refined sample preparation protocols, tailored fixture geometry, and adjustable pull speeds to accommodate varying thermal histories and draw ratios inherent to molded sections. Systematic variation of asymmetrical, temperature conditions, and clamping techniques revealed significant impacts on tensile strength, elongation at break, and strain distribution. Findings emphasize the necessity of customized testing frameworks for molded composite geometries and demonstrate that fixture alignment and thermal conditioning are critical to

Tensile and Fatigue Behavior of High Pressure Die Cast AE44 Magnesium Alloy at Elevated Temperatures2026-01-0234To be published on 04/07/2026
Tensile and cyclic behavior of high pressure die cast AE44 magnesium alloy have been studied at room temperature and elevated temperatures up to 350°C. Anelastic behavior has been found in both tensile and cyclic deformation at the temperature below 150°C. With increasing temperature, the anelasticity disappears, and tensile and cyclic behaviors become similar to other engineering materials, such as steels and aluminum alloys, i.e. the total strain contains only elastic strain and plastic strain. A method to determine the yield strength at 0.2% plastic strain (σ0.2) is proposed. By using the proposed method, the yield strength σ0.2 is higher than that determined using the traditional method, which is more suitable to the materials that do not exhibit anelasticity. It is believed that the anelasticity is closely related to twinning in Mg alloy, which disappears at elevated temperatures.

Novel Approach on Material Characterization Testing of Various Wiring Harness2026-26-05481/16/2026
The automotive wiring harness (length of 4-5 km) is a very important and complex system in the development of a modern car due to lot of new electric & electronic components and sensors. It is a very sensitive material unlike metals and is considered as a composite which is highly anisotropic in nature, as it consists of several different layers of copper/aluminum strands and insulation. Because of insulation, wiring harness exhibits viscous plastic behavior which is crucial in determining the durability and long-term performance of the cables. Material property has a crucial role in determining the behavior of wiring harness after assembly into the car. Wiring harness may undergo Bending, Torsion and Tension loads, causing the stress and strain in the individual electrical wires. The lack of CAE validation of the wiring harness routing may lead to extra costs for the automotive OEMs during product development. This study explains the novel method of Testing the Cables and Bundles

Effect of Flow Forming Process on the Mechanical Properties and Microstructure of GDC & LPDC Cast Aluminium Alloy Wheels2026-26-02981/16/2026
Aluminum alloy wheels have become the preferred choice over steel wheels due to their lightweight nature, enhanced aesthetics, and contribution to improved fuel efficiency. Traditionally, these wheels are manufactured using methods such as Gravity Die Casting (GDC) [1] or Low Pressure Die Casting (LPDC) [2]. As vehicle dynamics engineers continue to increase tire sizes to optimize handling performance, the corresponding increase in wheel rim size and weight poses a challenge for maintaining low unsprung mass, which is critical for ride quality. To address this, weight reduction has become a priority. Flow forming [3,4], an advanced wheel rim production technique, which offers a solution for reducing rim weight. This process employs high-pressure rollers to shape a metal disc into a wheel, specifically deforming the rim section while leaving the spoke and hub regions unaffected. By decreasing rim thickness, flow forming not only enhances strength and durability but also reduces overall

Comparative Study of ADC12, A356, and AlSi10Mg Alloys in Sand Casting of EV Battery Housing2026-26-02961/16/2026
This research investigates the applicability of ADC12 aluminum alloy in sand casting processes and compares its casting behavior and performance with that of conventionally sand-cast alloys such as A356 and AlSi10Mg. ADC12 is primarily utilized in high-pressure die casting (HPDC) and low-pressure die casting (LPDC) due to its excellent castability, pressure tightness, and favorable mechanical properties in thin-walled components. However, its use in sand casting is minimal globally, primarily due to the alloy’s high silicon and iron content, which can lead to poor feeding characteristics, increased porosity, and structural non-uniformity in non-pressurized molds. In this study, 3 mm thick test castings were produced using conventional sand casting methods, with particular attention to mold and core design to simulate challenging flow and solidification conditions. Comparative castings of A356 and AlSi10Mg were also produced under identical conditions to establish performance baselines

Thermo-Mechanical Fatigue Assessment of Cylinder Heads Using Advanced Simulation Techniques2026-26-04651/16/2026
Thermo-mechanical fatigue (TMF) is a critical durability concern for cylinder heads in internal combustion engines, particularly under severe cyclic thermal and mechanical loads. TMF-induced damage often initiates in geometrically constrained regions with high thermal gradients and can significantly reduce component life. As performance demands increase, understanding and mitigating TMF becomes essential to ensure the structural integrity and long-term reliability of engine components. This study presents a simulation methodology for evaluating thermo-mechanical fatigue (TMF), a temperature-dependent low-cycle fatigue (LCF) mechanism that arises from repeated thermal expansion and contraction under mechanical constraints, leading to cyclic plastic deformation and damage. The methodology consists of two key phases. Phase I involves global finite element (FE) simulations both thermal and structural to obtain temperature and displacement fields under rated and idle engine conditions

Evaluation of Shear Trim Edge in HSLA Steel for Automotive Application2026-26-02861/16/2026
Quality of the Shear Trimmed edge of HSLA 550 steels is significantly affected by process variations such as Shear Trimming Clearance, trim tolerance, burr height and clamping force. All these parameters largely influence the characteristics of the Shear Affected Zone, a region on sheet metal where it undergoes deformation during the trimming process. The Shear Affected Zone is predominantly vulnerable to failure due to work hardening and the effects of strain rate, induced by the tonnage during the trimming operation. To assess the edge ductility of these materials, Tensile, Fatigue Strength, Die Punch Clearance, Roughness and Hardness Tests are carried out. These tests are crucial for applications that demand high formability and resistance to edge failure. Virtual simulation of edge trimming operation using elastoplastic material models in LS-Dyna have been performed to gain insights into burr formation and damage evolution during shearing. These simulations act as a precursor to

Study the Tool Profile and Rotational Speed on Mechanical Attributes of FSW of Al 6063 Alloy05-19-03-00231/12/2026
Friction stir welding (FSW) of Al 6063 alloy plates of 6 mm thickness was investigated in the present study for exploring the mechanical attributes of the welded joints. The tool profile significantly influences the quality of joints produced by FSW. In the current study, the influence of tool profile and FSW process parameters on the FSW weld characteristics of similar joining of Al 6063 plates has been investigated. The effect of FSW tool rotational speed (TRS) and tool travel speed on the FSW weld properties, mainly microstructure characteristics, microhardness, and ultimate tensile strength (UTS), have been studied. Comparison of two different tool profiles, namely taper and cylindrical tool, has also been examined. The effect of transient temperature distribution has also been studied for varying FSW process parameters. When increasing the tool’s rotational speed from 800 to 1200 rpm at a fixed traverse speed of 80 mm/min, a rise in peak temperature is observed. Conversely

Color Filtering Software Enhances Material Strain AnalysisTBMG-5429312/1/2025
Innovators at NASA Johnson Space Center have developed a technology that can isolate a single direction of tensile strain in biaxially woven material. This is accomplished using traditional digital image correlation (DIC) techniques in combination with custom red-green-blue (RGB) color filtering software. DIC is a software-based method used to measure and characterize surface deformation and strain of an object. This technology was originally developed to enable the extraction of circumferential and longitudinal webbing strain information from material comprising the primary restraint layer that encompasses inflatable space structures.
Self-Healing Biodegradable Composites for Off-Highway Vehicles in Extreme Environments2025-28-021111/6/2025
Off-highway vehicles (OHVs) frequently operate in extreme environments—ranging from arid deserts and frozen tundras to dense forests and abrasive mining zones—where structural wear, impact damage, and environmental stress compromise their material integrity. Frequent repairs and component replacements increase operational costs, downtime, and environmental waste, making durability and sustainability key concerns for next-generation vehicle systems. This paper explores a novel class of self-healing biodegradable composites, inspired by biological systems, to address these challenges. The proposed materials combine bio-based resins, microencapsulated healing agents, and shape-memory polymers (SMPs) to autonomously repair microcracks and surface-level damage when triggered by thermal, UV, or mechanical stimuli. The design draws inspiration from natural self-healing systems such as tree bark and reptile skin, replicating their regenerative behavior to enhance structural resilience in OHVs

Optimization of Arc Welding Parameters for FB590 Hot-Rolled Ferritic-Bainitic Steel with 2.5 mm Thickness05-19-03-001810/31/2025
In this study, the optimization of robotic gas metal arc welding (GMAW) parameters for joining hot-rolled ferritic-bainitic FB590 steel sheets with a thickness of 2.5 mm was investigated. The main objective was to evaluate the effect of wire feed speed and welding speed on the penetration depth, throat thickness, and mechanical performance of the welded joint. A series of welding experiments were carried out with wire feed speeds ranging from 50 cm/min to 100 cm/min and welding speeds ranging from 5 cm/min to 15 cm/min. Tensile and microhardness tests were carried out to evaluate the structural integrity of the welded joints. The results show that increasing the wire feed speed significantly improves the weld penetration and throat thickness, especially at constant welding speeds. The most suitable combination was found to be 70 cm/min wire feed at 8 cm/min travel speed and 100 cm/min wire feed at 12 cm/min and 15 cm/min travel speeds. The microhardness in the heat-affected zone

Investigation of the Effect of Rotation Speed and Post-Weld Heat Treatment on Mechanical Properties and Structure of Friction Stir Welding AA6061 Joints05-19-02-00169/25/2025
This study aims at examining the effect of tool rotational speed on the microstructural and mechanical properties of friction stir welded joints of AA6061 aluminum alloy, both pre- and post-heat treatment. The quality of the joints was assessed initially through tensile, hardness, and charpy impact tests, as well as microscopic observations. During the second stage, solid solution heat treatments were conducted at 535°C, followed by aging on additional specimens welded at identical speeds. The latter underwent hardness tensile tests and microscopic examinations. A comprehensive assessment of the outcomes from various tests validated the influence of metallurgical phenomena, including recrystallization, precipitation, and structural defects on overall resistance. The results showed an improvement in strength, ductility, and impact energy was observed in the case of welding at high rotation speed (1400 rpm). At the same speed, ductility almost doubled after post-weld heat treatment

Effect of Casting Microstructure on the Mechanical Performance of Recycled EN AC-43200 Al-Si Alloy2025-01-03579/15/2025
This work investigates the influence of casting microstructure on the mechanical performance of ad hoc samples of recycled EN AC-43200 Al-Si alloy. Three batches are produced by modifying the casting process parameters (i.e., molten alloy temperature and in-mold cooling conditions) to obtain different casting microstructures. Room temperature tensile and high-cycle fatigue tests, coupled with metallography, X-ray tomography, and fatigue fracture surface analysis, are performed to elucidate the relationship between microstructural characteristics and mechanical properties of the investigated alloy. The findings indicate that casting pores and intermetallic precipitates play a pivotal role in influencing the mechanical behavior and performance of cast, recycled EN AC-43200 Al-Si alloy. Additionally, an inverse correlation between secondary dendrite arm spacing (SDAS) and both tensile properties and fatigue life is established.
