The continuum constitutive modeling for rate-dependent fracture of brittle microcracking solids is discussed. The rate-type constitutive equation that is proposed takes into account the rate effect on microcracking. It is applied to the finite element analysis of stationary and rapidly-propagating macrocracks under dynamic loading. The microcrack toughening effect is discussed, through the observation of the behavior of the general crack-tip energy-release parameter, the T*-integral.
