Abstract Scope |
Powder Bed Fusion (PBF) stands as a pivotal technology in additive manufacturing, renowned for its ability to produce intricate metal components with high precision. This study introduces a comprehensive elastoplastic thermomechanical simulation of the PBF process, integrating both isotropic strain hardening and cyclic hardening/softening effects. We developed an advanced simulation algorithm designed to accurately predict residual stresses and deformations, which are critical in determining manufactured parts' final performance, durability, and safety. Our findings reveal a 30 percent difference in the prediction of stress state values and residual stress when considering cyclic hardening/softening effects, particularly at higher scan speeds. These insights are instrumental in optimizing PBF parameters, ultimately reducing residual stresses and improving the quality of produced parts. |
