Abstract

This paper discusses the problem of surface crack growth and its modelling. The concept of root mean square stress intensity factors (RMS SIF) is discussed for the general class of semielliptical surface cracks and its advantage over the traditional two point (or multi-point) SIF approach in conjunction with the Paris law is emphasised. 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.
