To determine the underlying probabilistic distributions of the physical and mechanical property parameters of the mesoscopic representative volume element(RVE) and to form the probabilistic volume element(PVE) models,it is a quintessential problem in the elastic damage analysis of quasi-brittle materials by means of the damage micromechanics.

The damage process is accompanied by the acoustic emission(AE)for quasi-brittle materials such as rocks,concretes,ceramics and so on.

The study of the instability of quasi-brittle materials under the action of a non-stiff loading system is helpful to forecast the unstable failure of materials or structures and to extrapolate the intensity of catastrophic failures.
