摘要：

Laboratory measurements of volumetric strain and velocity in Westerly granite are analyzed to determine the physical nature of microcracks in the rock. The commonly used frictional 'sliding crack' model of dilatancy is examined in detail. The characteristics of an ensemble of sliding cracks which open with a stick slip motion cannot account for the observed 'memory' of the peak stress in cycling experiments. This analysis shows that the sliding crack is an unlikely mechanism for dilatancy.
