| Abstract: |
| Using the iso εθ line of concrete crack tip, the shape strain energy criterion of iso εθ line forⅠ Ⅱmixed mode crack was established by comparing with the predicted value in other theories and known experimental data.The results show that predicted value of this criterion is in agreement with known experimental data. |
| Key words: concrete mixed mode crack fracture criterion strain energy iso εθ line |
