THE UNIFICATION OF DAMAGE WITH FRACTURE
-
摘要: 本文讨论了连续损伤力学基础的缺陷,从微裂纹随机演化出发给损伤概念作出新的普适的统计定义,导出了损伤断裂几率的动力学方程,使损伤、断裂、统计、微观机理及宏观特性五者有机地相结合,从而有可能形成一个统一的损伤断裂微观统计理论。Abstract: The shortcomings of damage mechanics foundation are discussed. The new universal statistical damage concept is defined from stochastic evloution of microcracks (microvoi-ds) 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 is constructed.
