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

Convenient and accurate formulas for stress intensity factor distribution of semi-elliptical surface crack [PDF]
, 2021 In this paper, the stress intensity factor (SIF) formula FISE along the crack front of a semi-elliptical surface crack is studied. The exact SIF solution FISE is used by solving the hypersingular integral equation of the body force method discussed in ...

A novel weight function for RMS stress intensity factor determination in surface cracks [PDF]
, 2010 This paper discusses the problem of stress intensity factor determination in surface cracks. In particular, the concept of root mean square stress intensity factors (RMS SIF) is discussed for the general class of semi-elliptical surface cracks.
