A plane stress perfectly plastic mode I crack problem for a yield criterion based on the second and third invariants of the deviatoric stress tensor, II

David J. Unger

Vol. 4 (2009), No. 9, 1651–1656
Abstract

In the first paper with this title (J. Mech. Mater. Struct. 3:4 (2008), 795–807), the solution of a stress function of a mode I perfectly plastic crack problem was found analytically for two of the three sectors that comprise the solution of the problem for a yield condition based on the second and third invariants of the deviatoric stress tensor. Here an exact solution is derived for the remaining sector of this crack problem, which comprises the singular solution of the governing differential equation.
