Characterization of constraint of fully plastic crack-tip fields in non-hardening materials by the three-term solution (Q1302862)

The authors study the mechanic behavior of the \(J\)-\(A_2\) solution for a plane strain mode-I crack in very low hardening materials. The objective is to investigate the validity of \(J\)-\(A_2\) characterization, in an approximate sense, for fully plastic crack-tip fields in non-hardening materials. In particular, the authors study the constrains at the crack tip for several conventional specimen geometries and loading configurations in non-hardening materials.
