| Abstract: | The stress intensity factors of a crack at bimaterial interface are computed by using BEM and outward-smoothed stress method, and the results show good agreement with analytic ones. On top of that, this method is used to calculate the stress intensity factors of interface crack at the heel of gravity dam, and some useful conclusions are presented. |
