From: Premature failure of an additively manufactured material
a True stress vs. true strain curves for the SLM and cast samples. The inset shows the SLM and cast samples after tensile deformation. b Ultimate tensile strength of the SLM samples compared with the cast and other specimens from the literature. c Normalized work hardening rate (\(\Theta = (\partial \sigma /\partial \varepsilon )_{\dot \varepsilon }/\sigma\))15,42 against true strain for the SLM and cast samples. The dashed lines (green) in c show the possible point satisfying Considère’s criterion, where the work hardening rate is equal to true stress. The inset figures in c are typical ln σ– ln ε plots for the SLM and cast samples, indicating the strain hardening exponent n.
