Modelling and Analysis of Complex Shaped Cracks2026-28-0048To be published on 02/12/2026
This study offers a thorough analysis using finite element methods (FEA) to examine how fatigue cracks grow in three different materials: Structural steel , Titanium alloy (Ti Grade 2), and epoxy/aramid-based printed circuit board (PCB) laminates. Using ANSYS Workbench, we ran simulations under both static and repeated loading to understand how these materials fracture. The approach was based on Linear Elastic Fracture Mechanics (LEFM), employing the Maximum Circumferential Stress Criterion to predict where cracks might start and how they could spread. Also, the Equivalent Domain Integral (EDI) method helped us calculate the Stress Intensity Factors (SIFs) when cracks are under mixed loading modes. We modeled the growth of fatigue cracks using the Paris Law, relying on material-specific constants (C and m) drawn from previous studies and experimental tests. For example, titanium Grade 2 showed Paris Law constants with C values between 1.8 × 10⁻¹⁰ and 7.9 × 10⁻¹² m/cycle, and m values

Sustainable Machining of Aluminium Alloys: Experimental Insights into WEDM Process Optimization2026-28-0034To be published on 02/12/2026
The most advanced mathematics transforms aluminum alloys into one of the most highly intricate materials into practically any engineering application based on the mechanical properties of ductility and low fatigue sensitivity. The use of aluminum alloys permeates critical industries like aerospace and automotive, besides being strong contenders in other high-performance applications. Their inherent corrosion resistance certainly gives an edge to aluminum alloys for applications in rigorous service environments. Conventional manufacturing processes would not successfully create components with some geometrical complexity; hence, advanced machining processes are being developed. Among them is Wire Electrical Discharge Machining (WEDM), which is increasingly being adopted within the EDM family, as it efficiently machines hard and complex shapes at high accuracy. The present investigation deals with WEDM of aluminum alloy using Taguchi's design of experiments approach, while focusing on

Evaluating the Suitability of ADC12 for Sand Casting: Filling, Solidification, and Mechanical Properties2026-26-0296To be published on 01/16/2026
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

Effect of the Flow Forming Process on the Mechanical properties and Microstructure of GDC & LPDC cast aluminum alloy wheels.2026-26-0298To be published on 01/16/2026
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 production technique, 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 reduces overall wheel weight but also enhances strength and

Non-metallic inclusions in carburizing steels as a contributory factor for the formation of carbide net2026-26-0290To be published on 01/16/2026
The article deals with the issue of identifying structural defects that contribute to the formation of a carbide net during thermochemical treatment of steel parts, which negatively affects the mechanical properties complex of finished products. Based on the available data, a theory has been put forward regarding the influence of the present non-metallic inclusions in the carburizing steels structure on carbide formation process in the hardened layer. As an experimentally the samples have been produced from the varying chemical composition alloy structure carburized steel (0.17-0.23 % C, 0.17-0.37 % Si, 0.80-1.10 % Mn, 1.00-1.30 % Cr, 0.03-0.09 % Ti). During microstructure analysis of the samples it has been establish that non-metallic inclusions, in particular sulfides, contribute to the formation of carbides and carbide net in steel due to their high chemical activity with carbon. Thus, contamination of the metal of carburizing steels with non-metallic inclusions is not only a defect

The purpose of the study is to present the validation stages of the transmission bearing housings in a Formula SAE prototype and the redesign of the components to reduce mass. The objective was to design and implement bearing housings that are lightweight while withstanding the loads they are subjected to. A numerical simulation using the Finite Element Method (FEM) was conducted to analyze the behavior of the bearing housings, made of 7075 aluminum alloy, under the same boundary conditions as in the test bench. This simulation provided information on deformation and stresses and was used to determine optimal locations for strain gauge placement. Experimental bench tests were performed, applying forces ranging from 100 N to 600 N. With an application of a 600 N load, an experimental deformation of 1.77E-04 mm/mm was obtained, while FEM indicated 1.71E-04 mm/mm, demonstrating significant correlation, with a 3.4% margin of error.

Fractographic Analysis after Creep Testing of Ti-6Al-4V with Yttria and Niobia Co-Doped Zirconia TBC2025-36-005312/18/2025
The application of Thermal Barrier Coatings (TBC) has been widely utilized in aerospace turbines to enhance the operational temperature and thermal efficiency of titanium alloys, while preserving their properties such as low density, creep resistance, and corrosion resistance. TBC systems typically consist of a metallic substrate, a metallic coating (Bond Coat), a thermally grown oxide (TGO), and a ceramic topcoat (TC). This study investigated the fracture surface characteristics of Ti-6Al-4V with TBC after a creep test at a constant temperature of 600 °C, under stress levels of 125, 222, and 319 MPa, in order to understand the mechanisms involved. The TBC was composed of a NiCrAlY (BC) and a zirconia co-doped with yttria and nióbia (TC). The fracture characterization of the alloy after the creep test was conducted through stereoscopy and scanning electron microscopy. The fracture mechanism at 600 °C and 222 MPa was predominantly ductile, as evidenced by the presence of dimples and

Lightweight Design and Optimization of Multi-Terrain Multi-Functional Tracked Amphibious Vehicle2025-99-032412/17/2025
In view of the complex intertidal terrain challenges faced by offshore wind power maintenance, this paper optimizes the lightweight design of multi-terrain tracked vehicles. The structure was optimized by finite element analysis, and the maximum stress was 211.68 MPa ( lower than the safety limit of 230 MPa), and the maximum deformation was 5.25 mm, which ensured the stability and stiffness. Titanium alloy has the advantages of high strength, low density and corrosion resistance, which improves the durability of the frame while reducing the weight of the frame. Advanced manufacturing technologies such as phase transformation superplastic diffusion welding optimize the connection between TC4 titanium alloy and stainless steel. Modal analysis and optimization techniques refine the structural parameters and improve the complex load performance. The research promotes the lightweight of the frame and provides theoretical and technical support for the design of multi-terrain vehicles.

Higher-Strength, Higher-Toughness Die Cast Wheel Material using Recycled Aluminum2025-32-000711/03/2025
In an attempt to reduce CO2 release from alloy wheel production, we have developed an aluminum alloy for casting that satisfies necessary property requirements using recycled aluminum, but without heat treatment. The wheel is a critical safety feature of any vehicle, and it should have toughness and strength .In many wheels, virgin aluminum containing small amounts of impurities is used to maintain toughness, and heat treatment (T6), which is post-casting quick heating and quenching, is applied to provide strength. At the start of this project, we focused on two wheel-manufacturing processes, production of virgin aluminum and heat treatment, from which a large amount of CO2 is released. By switching to recycled aluminum, CO2 was reduced to one-ninth the original amount. The issue with recycled material is that impurities grow in the metal structures as intermetallic compounds and this reduces toughness. To deal with this issue, we have chosen high-pressure die casting (HPDC), in which

Influence of Laser Sintered Process Parameters on Crystalline Characteristics and Mechanical Properties of AlSi10Mg Alloy05-19-03-001911/03/2025
The present study examines the influence of process parameters on the effect of strength and crystalline properties of AlSi10Mg alloy with laser sintered process. A detailed work was carried out with the effects of varying the laser power, scan speed, and hatch distance on crystalline structure, hardness, and surface roughness. From the analysis, the improved surface quality and mechanical performance were achieved with a scan speed of 1200 mm/s, a laser power of 370 W, and a hatch distance of 0.1 mm. An increase in hardness, improved surface finish, and reduced porosity was observed with decreased hatch distance. However, the balanced results were obtained for scanning speed of 1200 mm/s and laser power of 370 W. The ideal processing conditions decreased the crystalline size, increasing the overall material strength, when crystalline analysis was carried out. The higher scanning speeds supported improved grain refinement and heat diffusion, with the poor hardness value. With the lower

A Microstructural Comparison of NiCoCrAlY Superalloy Coatings Manufactured by Combustion Flame Spray and High-Velocity Oxygen Fuel Processes05-19-03-001710/15/2025
NiCoCrAlY powders were thermally sprayed by combustion flame spray (CFS) and high-velocity oxygen fuel (HVOF) processes on IN 718 alloy substrates. Experimental parameters were fixed to manufacture coatings with a thickness about 200 μm. Microscopy and X-ray diffraction analyses were performed to reveal microstructural characteristics of both developed CFS and HVOF coatings, and it was observed that they were formed by a lamellar morphology composed of β and γ phases. The analyses also revealed lower porosity in the coatings produced by HVOF process while was compared with CFS process. While a microstructure composed of like-deformed powder was developed in HVOF process, in the case of CFS a building layer-by-layer was characteristic. Vickers hardness tests were also performed, and it was found that coating developed by HVOF process showed quite higher hardness values compared with those measured on the coatings developed with the CFS process, nonetheless this difference was small
