Abstract :
An inclined subsurface crack subjected to a moving compressive load is analyzed with the finite element method (FEM), considering friction on the crack surface. The fracture parameters for the inclined subsurface crack are evaluated numerically for various cases such as different inclined angles and changes in the coefficient of friction on the crack surface. The effects of the inclined angle and the coefficient of friction on the fracture parameter are discussed. The difference between the behaviors of the parallel subsurface crack and the inclined subsurface crack is also examined.
