Fatigue life prediction of the additively manufactured specimen

Abstract Additively manufactured specimens generally exhibit comparable or improved tensile properties, such as yield stress, ultimate strength, and uniform elongation, compared to conventionally specimens. However, the defects that are typically present in additively microstructures result inferior fatigue performance. A representative volume element-based modeling technique incorporating these has been used predict reduction endurance limit of an stainless steel material. This physics-based model can clearly demonstrate poor performance based on micro-plasticity generated by microstructure under cyclic loading. Neuber analytical also applied life materials for a given stress amplitude. Both prediction from finite element very close experimental limit.
