- Abstract
This study presented a numerical methodology to elucidate the local mechanical response of the surface layer during and after an EDM electrical discharge, aiming to refine the numerical prediction of the residual stress and strain hardening induced by this process. Advances in models, loads, and boundary conditions were proposed and simulated using the ABAQUS/Explicit computational software. A coherent thermomechanical model was formulated, incorporating Grüneisen's hydrodynamic behavior coupled with the Johnson-Cook plasticity model. Numerical findings highlighted the efficiency of the uniform heat flux distribution model in predicting residual stresses accurately.
