Abstract
The present study intends to evaluate the ratcheting response of the additively manufactured (AM) samples made of Al 4043, SS316L, and Ti–6Al–4V alloy through hardening rules and finite element analysis. The hardening framework consisted of Ahmadzadeh‐Varvani (A-V) kinematic hardening rule and an isotropic hardening description by Lee-Zavrel (L-Z). Yield surface evolution was evaluated for (i) AM samples taken from mid and top sections of the 3D printed plate, and (ii) heat-treated samples. The Chaboche’s materials model was employed to assess ratcheting of AM samples through use of finite element method. The choice of hardening models affected yield surface translations over the loading process. The predicted and simulated ratcheting curves were found in close agreements falling below those of measured values.
