| Abstract: |
| In this paper, a new method of dynamic fracture analysis of three-point bending beam with an edge crack is presented by applying the elementary bending theory of beam and the line-spring model. This method can simplify calculation, and the numerical results show that it has high precision. |
| Keywords: dynamic fracture, three-point bending beam, line-sping model |
