Abstract
The new simple and effective grid remeshing method on crack propagation in brittle materials is successfully introduced which is under uniaxial compression. Numerical analysis is applied to brittle materials of a single pre-existing crack considering various dip angles, lengths and friction coefficient. According to linear elastic fracture mechanics theory, we introduce node moving method to guarantee the good shape of the grid in the process of crack growth, and set contact element between the friction surfaces, and then get the crack tip stress intensity factor by using quarter singular element. The influence of length, angle and friction coefficient on crack propagation is quantitatively described. The method is consistent with the experimental results and is effective in 2D problems.
