NUMERICAL MODELING OF MODE I CRACK PROPAGATION IN ROCKS WITH MESHLESS METHOD
It is difficult to simulate crack propagation in rock and implement essential boundary conditions using the traditional meshless method. Kriging interpolation procedure is used instead of the least squared procedure to construct a function which has the property of the Kronecker 8 function and the essential boundary conditions so that it can be easily imposed. The proposed method can effectively simulate singular stress fields near the crack tip and discontinuous problems such as crack growth. The problem with mode I crack in rock is analysed, and the path of crack growth is simulated by the proposed method. The results show that the numerical results are in agreement with the experimental results.
