摘要
本文建议了一种在外界载荷作用下,在固体中产生的微损伤的统计演化的理论描述方法。特别是,作为一个例子,讨论了理想微裂纹系统,以便了解在微裂纹成核和扩展过程中,损伤演化的基本行为。本文也简单讨论了有关的平均损伤函数。
The paper presents a principal formulation of statistical evolution of mic-rocracks, occurring in solids, subjected to external loading. In particular, the concept of ideal microcracks is elaborated, in order to describe the fundamental features of damage resulting from nucleation and extension of microcracks. Relevant average damage functions are also discussed.The paper presents a principal formulation of statistical evolution of mic-rocracks, occurring in solids, subjected to external loading.
