Abstract:
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. The weight
function SIF derivation method is considered problems with the existing techniques are
highlighted, and a novel technique for the derivation of the RMS SIF weight functions for
surface cracks is presented and results are compared with numerical solutions for a variety
of loadings and geometries.
