Quantification of tensile damage evolution in additive manufactured austenitic stainless steels

This study aims to quantify the material behavior, mechanical response, damage evolution and fracture characteristics of an austenitic stainless steel fabricated by Laser Engineered Net Shaping (LENS™). An internal state variable (ISV) plasticity-damage model is used to capture the effects of microstructural features, associated with the manufacturing process, on mechanical properties.
