| Abstract: | The energy release rate and failure criterion for mixed mode are investigated by means of the method of equivalent linear crack extension.As a numerical example,the slanting crack in uniaxially tensile plate is considered.As compared with the experimental results,the analytical solution and finite element results obtained on the interaction curve and angle of cracking are satisfactory. |

| Keywords: | energy release rate failure criterion interaction curve angle of cracking |
