A Treatment of Inelastic Deformation Around a Crack Tip due to Microcracking

A numerical procedure is described for modeling the number and distribution of microcracks around a crack tip as a function of the applied stress intensity. The procedure accounts, approximately, for microcrack‐microcrack and microcrack‐crack interactions. Starting with an array of sites where microcracks can form, the model computes the generation rate of microcracks with increasing stress intensity. The interaction between several neighboring …
