Asymptotic near-tip fields are analyzed for a plane strain Mode I crack propagating dynamically in non-associative elastic-plastic solids of the Drucker-Prager type with an isotropic linear strain hardening response. Eigen solutions are obtained over a range of material parameters and crack speeds, based on the assumption that asymptotic solutions are variable-separable and fully continuous. A limiting speed, beyond which a tendency to slope discontinuity in angular distributions of stresses...[Show more]
