Fracture Problems in Pressure Vessels and Reinforced Pipes

本研究将解决三个重要问题：（1） 材料不相似性对包壳裂纹的影响 管道和压力容器;（2）小表面缺陷的建模 在一般载荷条件下的薄壁部件中;以及 (3)缺陷产生的断裂的基本微观力学问题 在复合材料的界面区域。 一种新的分析方法 已开发解决积分方程，并显示 在解决这些问题的应用中有相当大的希望 三个问题。

This research will address three important problems: (1) the effect of material dissimilarity which occurs with cracks in clad piping and pressure vessels; (2) modeling of small surface flaws in thin-walled components under general loading conditions; and (3) basic micromechanics aspects of fractures produced by flaws at the interface regions in composites. A new analytical method has been developed for solving integral equations, and shows considerable promise in application to the solution of these three problems.
