The Initiation of Environmentally Assisted Cracking in Semi-Elliptical Surface Cracks [PDF]
Journal of Pressure Vessel Technology, 1998 A Criterion to predict under what conditions EAC would initiate in cracks in a high-sulfur steel in contact with low-oxygen water was recently proposed by Wire and Li (1996). This EAC initiation criterion was developed using transient analyses for the diffusion of sulfides plus experimental test results. The experiments were conducted mainly on compact

Modelling of the fatigue strength degradation due to a semi-elliptical flaw
Forces in Mechanics, 2021 Due to the fulfilment of modern operational requirements and time-consuming of complex fatigue responses computation, the surface micro-flaw analysis in large moving systems is still one of the challenging tasks. Thus, the present research work discusses
