| Abstract: | SOLID65 element and smeared crack model in ANSYS were used in analysis of crack growth at the interface between dissimilar materials.The cohesion at the interface and the ratio of strength k between two materials were discussed.The numerical simulation agree with the test results,which testified that it is feasible to apply ANSYS program to analyze crack growth at the interface between dissimilar materials. |
