| The Maximum Circumferential Strain Fracture Criterion for Mixed Mode of Concrete |
|
|
| Abstract: |
| In this paper,the maximum circumferential strain fracture criterion is proposed with a comparison of the maximum circumferential stress criterion and the strain energy density theory.The comparison indicates a good agreement between the experimental results and the prediction from the theory of maximum cricumferential strain criterion. |
| Key words: concrete,fracture criterion,fracture,maximum circumferential strain |
