In this paper the asymptotic solution to the plane stress dynamic plastic field surrounding a propagating crack tip is given. The perfectly plastic model and Mises yield condition as well as J2 flow theory are adopted. The force of inertia is considered in the equations of motion. The asymptotic exp

The combined effects of large deformation and material inertia on the displacement gradients are analyzed for rapid mode III crack propagation. The constitutive model is linear at small strains, but the stress level cannot increase beyond a critical level. Steady-state dynamic strain fields are pres
