Abstract
Fast propagation of a semi-infinite crack in a Perzyna-type material is investigated by two different approaches. First, the asymptotic crack tip field is considered. The field quantities are determined and the dependence on material parameters and crack speed is discussed. Applying a strain criterion a K(v) curve is derived for small scale yielding. In the second part, a damage yield strip model for stationary crack growth is described. Numerical results are presented including the dependence of the stresses, the crack driving force and the temperature distribution as a function of crack velocity.
