New Trends in Rock Mechanics

  • Published:
International Applied Mechanics Aims and scope

Abstract

Some new results in rock mechanics and some applications are presented. First, it is shown how an elastic/viscoplastic nonassociated constitutive equation can be derived for rock-like and particulate materials. This constitutive equation is based on the fundamental concept of compressibility/dilatancy. Damage and microcracking energy are discussed. Examples are given to demonstrate that it is possible to predict where the rock near underground openings is dilatable and where is compressible, where and when short-term or long-term failure is to be expected, the amount of rock involved in evolutive damage, etc.
