Laser–arc hybrid welding (LAHW) is known to achieve more stable processes, better
mechanical properties, and greater adaptability through the synergy of a laser and an arc …

Classical calibration procedures for phenomenological thermo-elasto-viscoplastic
constitutive models usually involve a large number of tests to identify all the material …

The thermal effect of laser welding degrades the local material properties, and this inevitably
leads to thermal deformation and thermal residual stress in welded joints. In this study, the …

In recent years, to reduce cars costs, research has been conducted on dual-phase steels
with low manganese content (below 1.0%). This study investigated the influence of …

The accumulation of residual stress during welding and additive manufacturing is an
important effect that can significantly anticipate the workpiece failure. In this work we exploit …

Anticipation of the critical cutting condition for the transition of continuous chip to serrated
chip is a fundamental task in machining of ductile metallic material. In this study, the …

In this paper, a flow stress model of ultra-high-strength steel 1700MS was developed for
laser welding. The model considered the material behaviors of strain hardening …

The Charpy impact test behavior of base metal, weld metal, and heat‐affected zone for 6061‐
T6 and 7075‐T651 aluminum alloy welds was analyzed. Force versus time curves of welded …

The analysis and optimization of rapid or severe material forming process, where high
gradients of plastic deformations, strain rates and temperatures are reached during the …

In this work, a three-dimensional (3D) time dependent finite element method is used to
simulate the thermo-mechanical behavior of laser welded joints. Laser welding of two …
