Simulation Analysis of the Mutual Influence of the Stress Intensity Factor on the Multiple Blisters Caused by Hydrogen Induced Damage

摘要：

　　Hydrogen blisters are taken as the research object by using the finite element software ABAQUS.The stress intensity factors of blister cracks are numerically calculated at varying depths and different edge distances for established three-dimensional finite element models of single-blister and double-blisters,respectively.The mutual influence of the stress intensity factors of the multiple blisters is obtained.It shows that the blister crack is easier to expand when the crack is closer to inner wall of the cylinder.Whats more,the crack growth rate increases firstly and then decreases as the increasing of the distance between two blisters cracks.The investigated result is of great reference value for predicting the trend of blister crack growth.
