摘　　要：在高压容器应用领域,钛-钢复合层板解决了高压容器存在的一些问题,但是其在高压容器的实际应用中随着环境的变化,表面容易出现裂纹及相关凹陷。因此,试图利用数值模拟的方法探析钛-钢复合层板材料压力容器的裂纹扩展规律,旨在促进复合层板压力容器疲劳破坏准则的建立,提高钛-钢复合材料层板的应用水平。In the application field of high pressure vessel,titanium steel composite material solves some disadvantages of high pressure vessel.However,due to the actual application of titanium steel composite laminates in high pressure vessels,cracks and related dents are easy to appear on the surface with the change of environment,based on this,this paper attempts to analyze the crack propagation rule of titanium steel composite laminates pressure vessels by numerical simulation.The purpose is to promote the establishment of fatigue failure criteria for composite laminate pressure vessels and promote the application level of titanium steel composite laminates.
