Abstract

The near-tip asymptotic stress fields around an interface crack between an elastic-perfectly plastic solid and a rigid substrate are members of a family parameterized by ζ0, which depends on the phase angle and magnitude of the complex stress intensity factor and bimaterial properties. A new family of three-sector slip-line solutions is found in addition to the existing two-sector field and the family of four-sector fields. The finite element study confirms the existence of this new family, the two-sector solution, and only one member in the four-sector family. The finite element analysis also confirms the existence of elastic sectors near the interfacial crack tip.
