Abstract:
Determining st ress intensity factors is an important content of f racture mechanics. Taking into account of singularity of st ress and strain at the tip of crack, stress intensity factors of thick w alled cylinder under high inner pressure are found by stress and displacement of f inite element method. And the accuracy of these two methods is studied in comparison w ith boundary collocation method. Meanw hile, the rules of the st ress intensity factors w ith the change of crack depths and size of thick w alled cylinder are studied.
