(2) For I Propagating Crack. As sticky introduced. eliminate the plastic shock wave. and when characterization of crack Mach 10 speed, the dynamic solution can be subject to degradation, static solution. prove that the quasi-static solution is a special case of dynamic solutions. (3) used viscoplastic model to study aspects of the crack tip field is more reasonable and practical.
