Laser cutting is widely employed in the fabrication of structural‐steel components, yet the extreme thermal gradients generated during processing can induce tensile residual stresses that threaten dimensional stability and fatigue resistance. Although numerous studies have evaluated thermal behavior, surface morphology...
This paper presents a comprehensive thermo-mechanical analysis of laminated composite sandwich plates, focusing on bending deformations and buckling stability under combined thermal and mechanical loading. A First-Order Shear Deformation Theory (FSDT)-based formulation is employed, and a finite element model is develop...
:Laser-assisted machining offers significant advantages in the machining of difficult-to-cut materials. This paper presents an experimental investigation and FE simulation of laser-assisted turning (LAT) of H13 tool steel in longitudinal and face-turning operations. The effect of cutting speed and surface temperature o...
This study investigates the thermo-mechanical behavior of AISI 4140 steel and Inconel 718 during direct-drive rotary friction welding using finite element analysis and experimental approaches. The welding was modeled under rotational motion of the Inconel 718 specimen combined with axial compressive loading applied to...
The accurate prediction of the large-strain thermomechanical response of shape memory polymer (SMP) beams is challenging because geometric nonlinearities must be coupled with temperature-dependent viscoelastic and viscoplastic mechanisms, including plastic softening. This study develops a semi-analytical framework for...
