โœฆ Synopsis

An asymptotic analysis of the near tip fields is given for a steadily propagating crack. The power hardening material is characterized by J2 flow theory as well as deformation theory. A further condition for steady state crack growth is obtained. By using a new path independent integral, explicit results are given for the order of the crack tip singularity. It was found that the singularities calculated by using the different material models are not the same.

Stress intensity factors have been determined directly for certain special crack problems with the help of J or other path-independent integrals. Such procedures have not been used successfully in what are perhaps the most classical of all crack problems: those in two dimensions involving a crack of
