Mode I crack propagation in elasto-plastic pressure-sensitive materials

Mode I steady-state, quasi-static crack propagation is analysed for elastoplastic pressure-sensitive solids. Reference is made to the incremental small strain elastoplasticity obeying the Drucker-Prager yield condition with associative flow law. The asymptotic crack-tip fields are numerically obtained for the case of linear-isotropic hardening, under plane stress and plane strain conditions.
