Abstract

The continuum constitutive modeling for rate-dependent fracture of brittle microcracking solids, which was described in Part 1 of this paper, is applied to the finite element analysis of stationary and rapidly propagating macrocracks under dynamic loading. The microcrack toughening effect is discussed, along with the influence on it of the size of the microcracked process zone and the various parameters in the microcrack density evolution equation, through the observation of the behavior of the general crack-tip energy-relase parameter, the T integral.
