摘要
作为起裂控制设计方法的补充,经10多年的努力,已逐步形成了以断裂动力学为基础的止裂控制设计方法.本文讨论了这种新的断裂控制设计方法的梗概及其中的主要力学概念.
The crack arrest control design method based on the dynamic fracture mechanics as a complement of the crack initiation control design method has taken shape gradually in the last more than ten years. In this paper, the outline of this new fracture control design method and its main mechanics concepts have been discussed.
