ABSTRACTFatigue life assessment of metal additive manufacturing (AM) products has remained challenging due to the uncertainty of as–built defects, heterogeneity of the microstructure, and residual stress. In the past few years, many works have been

To investigate the crack growth behavior in a cladded structure, a numerical simulation method based on the extended finite element method (XFEM) was developed. This method employs 8-node hexahedral continuum elements enriched only with the Heaviside

The parallel steel wires used in arch bridge suspenders experience random corrosion damage on their surfaces during service. Corrosion damage, including micro-cracks, pitting, and a combination of both, leads to significant stress concentration under
