Defects in additive manufactured metals and their effect on fatigue performance: A state-of-the-art review

Niloofar Sanaei et al.

Summary: Additive manufacturing is emerging as an alternative method for producing unique and complex parts, with fatigue performance being a key consideration. Defects such as Lack of Fusion, porosities, and un-melted particles can affect fatigue performance, but can be minimized through process optimization and post-processing. Analytical techniques can reduce the need for costly fullscale testing for assessing reliability in fatigue performance.

Defect-based fatigue life prediction of L-PBF additive manufactured metals

Niloofar Sanaei et al.

Summary: This work presents a computational framework for predicting the fatigue life of two metal specimens, considering different treatment conditions and defect sizes. Unlike the commonly assumed crack growth mode in the literature, the appropriate crack growth mode based on the observed failure mechanism is used for fatigue life predictions. Good correlations between experimental results and prediction curves are demonstrated by using Extreme Value Statistics and equivalent defect size based on Murakami's method for approximation of the initial defect size.

Summary: This study investigated the fatigue behavior of two commonly used AM metals under different surface roughness conditions. It was found that factors such as defects and residual stresses resulting from the AM process may significantly impact the fatigue performance of parts.
