โฆ Synopsis
The shortcomings of damage mechanics foundation are discussed. The new universal statistical damage concept is defined from stochastic evolution of microcracks (microvoids). The kinetic equation of damage-fracture probability is derived. The damage, fracture, statistics, microscopic mechanism and macroscopic properties are connected organically with one another, and the unified microscopic statistical theory of damage fracture may be constructed.
