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

Wire Arc Additive Manufacturing (WAAM) is a cost-effective and scalable metal additive manufacturing technique widely used for fabricating large metallic components. However, surface finish remains a critical challenge, especially for structural applications where post-processing needs to be minimized. This study focuses on optimizing key process parameters to improve the surface finish of ER70S-6 steel structures fabricated using the WAAM process. Experiments were designed using a statistical approach to systematically vary parameters such as wire feed rate, travel speed, voltage, and inter-pass cooling time. Surface roughness was measured using standard metrology tools, and the results were analyzed to identify the most influential parameters. An optimized parameter set was proposed based on the experimental outcomes, leading to a significant reduction in surface roughness without compromising the structural integrity of the deposited material.

Steel-based Laminates for Lithium-ion Pouch Cell of Electric Vehicles2026-26-0186To be published on 01/16/2026
Aluminium foils have gained traction with EV battery manufacturers for their pouch cell format. Over the years it has evolved as a material of choice, but it is still plagued by issues of stress concentration, swelling due to lower strength and stiffness of base aluminium layer. Preliminary investigation revealed that laminates using steel foil material (thickness <0.1mm) could be a potential candidate for EV pouch cell casing. Thus, steel-based laminate was developed meeting key functional requirements (e.g. barrier performance, insulation resistance, peel strength, electrolyte resistance, formable without cracking at edges, and heat sealing compliant). This innovative patented steel-based laminate was further used to manufacture pouch cell prototypes (maximum capacity 2.5Ah) for key performance tests (e.g. cell cycling, nail penetration and thermal runaway). The study paves the way for a low cost, sustainable and flexible yet strong steel-based laminate packaging material solution

Balancing global and local formability properties through Nb microalloying2026-26-0303To be published on 01/16/2026
David Martin, CBMM Asia Bernardo Barile, CBMM Europe BV Caio Pisano, CBMM Europe BV Automotive high strength steels have specific microstructure-dependent forming characteristics. Global formability is generally associated with high uniform strain values which imply good drawability and stretch forming properties driven by pronounced work hardening. Local formability on the other hand is often measured by various fracture strain values—generally higher in single phase steels. In this respect, the so-called ‘local/global formability map’ concept has been established not only to provide a comprehensive methodology to characterize existing automotive steels but also to enable improvement strategies toward more balanced forming characteristics. Niobium (Nb) microalloying is a powerful tool to achieve both property improvement in general and property balance in particular. More than two decades of research has demonstrated that Nb-induced microstructural optimization is applicable to HSLA

Hydrogen Embrittlement in Galvanized High Carbon Steel Components of Automotive Seat Slider Assembly2026-26-0302To be published on 01/16/2026
This research paper investigates the failure of an isolator clip used in the seat slider assembly, which guides and restricts the sliding motion of the tooth bracket within the seat. The component is made of C80 high-carbon spring steel, known for its high strength. According to the manufacturing process details, zinc plating was applied to the component for corrosion protection, as confirmed by EDS analysis. A fractographic examination of the failed part revealed a brittle, intergranular fracture morphology with visible cracks. Certain areas also exhibited micro-void coalescence, indicating a dimpled fracture surface. The primary failure mode was intergranular (IG) fracture. The delayed fracture was attributed to intergranular fracture mechanisms, micro-void coalescence, and the high strength of the steel, which made the component susceptible to hydrogen embrittlement. Hydrogen embrittlement occurs when hydrogen atoms become trapped along the grain boundaries, where they form hydrogen

Evaluation of Shear Trim Edge in HSLA Steel for Automotive Application2026-26-0286To be published on 01/16/2026
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

Research on Invasion Line Control of Deep Foundation Pit Diaphragm Wall Excavation Based on Space-time Effect2025-99-031612/17/2025
The study focuses on the management of deep foundation pit excavation, influenced by temporal and spatial factors, in the context of the challenging environmental circumstances posed by the high-water-level silty soft clay along the Yellow River's northern shore, as part of the Jinan urban rail transit initiative. The subsequent inferences have been made: (1) Throughout the digging phase, issues such as excessive digging and delays in installing steel reinforcements occur, while the subterranean diaphragm wall tends to shift significantly inward within the excavation area due to the disparity in pressure between the water and soil inside and outside. (2) During the building phase, managing wall distortion is imperative, and an enhanced preliminary force should be applied to the support's axial component at points of significant deformation, guaranteeing an excess coefficient for both the support rigidity and the continuous subterranean wall rigidity.

The Simulation Study of Support Schemes for Transition Zones in Double-Fault Tunnels2025-99-044312/10/2025
When a tunnel passes through the transition zone between two faults, different support schemes have varying impacts on the deformation of the surrounding rock. This study, based on the Zhangzhuang Tunnel's double-fault area, establishes a numerical simulation model using Midas GTS NX to compare and analyze the effects of an enhanced support scheme versus a standard reinforcement scheme. The results indicate that when the non-reinforced support scheme is applied throughout the tunnel, the settlement of the transition zone's crown is 5.7 mm, only 0.27 mm greater than that of the reinforced scheme. Additionally, the variation in support stress in the transition zone between the two schemes is minimal. This demonstrates the feasibility of adopting the non-reinforced scheme, which reduces the number of steel arch frames, enhances construction efficiency, and provides a reference for future construction of small-section tunnels in double-fault conditions.

“Reduction in Product Development Time by Field-To-Lab Simulation”2025-28-028211/06/2025
Puddling is a crucial process in rice cultivation, involving the preparation of the soil in a flooded field to create a soft, muddy seedbed. There are two classifications for puddling: full cage and half cage. Full cage puddling involves replacing the rear wheels of the tractor with steel paddle wheels, which are used to till the rice paddies directly without any additional implement. In the half cage puddling, the rear wheels remain on the tractor, and a smaller cage or paddle wheel is attached to the outside. Considering the field size, the operator often releases the clutch very quickly after a speed or direction change. This generates torque spikes, which are harmful to Transmission Gears and Clutches. This can lead to gear teeth bending fatigue failure due to repeated higher bending stresses. In this paper, a study related to how to reduce overall product development time by simulating bending fatigue failure of gear in lab environment is presented. A systematic approach is used

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.

SiC Power Delivery for ‘Big Iron’ Medical DevicesTBMG-5399110/01/2025
“Big iron” instruments, aka diagnostic radiology equipment such as x-ray, ultrasound, and CT scanners, are indispensable for diagnosing and guiding treatment for an array of conditions from tumors to arthritis to fractures. While a tremendous asset for hospitals, these instruments are traditionally large, heavy, power hungry, and expensive. They are also difficult to acquire, install, and use.
The economics of lightweighting in heavy-duty vehicles25TOFHP10_0710/01/2025
Like those in many other industries, truck and off-highway vehicle manufacturers face the challenge of producing quality components and maintaining productive processes while also generating a better bottom line. Improving employee training, simplifying complex operations and implementing better workflows can all help generate efficiencies. While not a new concept, lightweighting - in this case, reducing the weight of parts through the substitution of traditional steel with high-strength, thinner steels - can also be a viable answer to a better vehicle. As a rule of thumb, when manufacturers double the strength of the material through lightweighting, it is possible to reduce the weight of the part by one-third. That weight reduction can then lower the cost per part for greater profitability per piece of equipment and greater annual savings.
