Abstract
Mode I steady-state, quasi-static crack propagation is analysed in elastoplastic pressure-sensitive solids obeying the Drucker-Prager yield condition. The asymptotic crack-tip fields are numerically obtained with reference to the incremental small strain theory, in the case of linear-isotropic hardening, under plane stress and plane strain conditions. The determination of the stress and strain anear-tip fields is fundamental for the understanding of fracture in ceramics, amorphous rocks at low temperature and concrete.
