Abstract
The effect of residual stresses can be beneficial or harmful depending on their magnitude, type and distribution. This research work applied the isotropic and kinematic hardening models with different strain rates (0.001-100 s-1) to simulate the non-linear mechanical behavior of Twinning Induced Plasticity (TWIP) steel microalloyed with titanium. A finite element (FE) thermo-mechanical model was employed to analyze the welding thermal cycle in the TWIP-Ti steel. The numerical prediction of resid...
