Abstract

An asymptotic analysis of the near tip fields is given for a steadily propagating crack. The power hardening material is characterized by J 2 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.
