Revisiting the Hult–McClintock closed-form solution for mode III cracks

Zhi-jian Yi

Vol. 5 (2010), No. 6, 1023–1035
Abstract

The well-known closed-form solution given by Hult and McClintock for an antiplane crack in an elastic-perfectly plastic material is reconsidered using the crack line analysis method. A precise elastic-plastic solution near the crack line region, different from Hult and McClintock’s, is deduced by matching the general solution of the plastic field with that of the exact elastic field. It is verified from the deduction that the Hult–McClintock elastic-plastic solution is inadequate for many purposes.
