| Abstract: | The lamage character of Nanling marble is analysized.According to the brittle damage theory,the curve between the damage energy release rate and damaeg variable is acquired.The theory analysis is agreed with the test.The dynamic fracture fractal model is built which belongs in the couple of driving crystal and penetring crystal of Nanling marble.The fractal dimension of crack expansion and the formular of Griffith critical expanding force is also obtained. |
