Several velocity regions, distinctly different as regards crack edge propagation characteristics, can be distinguished. The simplest case is mode III with only the subsonic and the supersonic regions. For modes 1 and II four different regions can be recognized. When analyzing the near-tip field at l
In this paper the mode I dynamic crack-tip field propagating in perfectly plastic solid is studied. The two dimensional constitutive relation is derived from the Mises yield condition and constrain condition E z = 0. Two stress functions +, q0 are introduced for plastic domain. By means of analysis
A complete development for the higher-order asymptotic solutions of the crack tip fields and finite element calculations for mode I loading of hardening materials in plane strain are performed. The results show that in the higher-order asymptotic solution (to the twentieth order), only three coeffic
