A study on additive manufacturing of a 304L stainless steel

Part distortion and residual stress development are two major issues that hinder the industry’s application of the Laser Powder Bed Fusion (LPBF) process. This research will study the formation of residual stress and the distribution of stress fields during the LPBF process using finite element method (FEM) modeling. A sequentially coupled thermo-mechanical FEM model will be developed using ABAQUS FEM software. This study will investigate the distribution of stress components (Sxx, Syy, and Szz) during the LPBF process. Also, the effect of laser power, laser speed, and preheating on the residual stress will be studied.
