Title: The Stress Intensity Factor and Angle of Crack Propagation Using the Energy Method─A Microcomputer Software of Fracture Mechanics
Abstract: In order to solve the problem using the theoryof fracture mechanics find the remaining life of parts withcrack in engineering aPPlicotion, using finite element methodto find the stress intensity factor factor and angle of crack tion is met with attention. In this article,the change ofsystem petential energy △U, when the crack length propagatesfrom a to a+△a, was used for obtaining strain energy relrate G and sires intensity factor K. Calculating result can beindicated, there is high precision and single and direct whileusing this method. Meanwhile the angle of crack propagationby finding value of energy release rate G. can befoed. be to the common of calculation programme, thissoftware can be used widely to solve the problem in engineer ing componets with crack and becoming a prctical tool ofanalysing component security.
