| Abstract: | A new boundary integral equation is introduced to analyze plane elastic problems with cracks, and the boundary element numerical method based on this equation is established. The program is written using FORTRAN for Griffith crack problem, and STF is obtained by the relationship between the stress intensity factor and the dislocation density on the tip. |

| Keywords: | cracks fracture mechanics stress intensity factors integral formulation boundary elements |
