The problem of propagating crack characterization is examined for a case of a stochastic brittle medium. Crack-damage interaction and its influence on fracture kinetics are accounted for by means of continuum damage mechanics and stochastic values of stress intensity factor. The two-dimensional prob

Prefatigue hysteresis effects on viscoelastic crack-propagation velocity were investigated through velocity-gauge techniques at different temperature levels. It was found that prefatigue effects accelerate elastic predominance in viscoelastic dynamic crack propagation, approaching elastic brittle fr
