Local Approach of Fracture Applied to Anisotropic Damage Parameter

Abstract

In the present study, the analysis method of the propagation behavior for the multiply distributed cracks is proposed by means of local approach of fracture (LAF). It is difficult to calculation the propagation of multiply distributed cracks based on fracture mechanics because it takes many calculation time and the cast. The simple analysis method is therefore required. Though LAF is generally applied to isotropic damage parameter, the result of the FE-analysis using isotropic damage parameter because the dynamic effect of actual cracks has anisotropic. So we propose the simple method based on damage mechanics to conduct the finite element analysis method considered the anisotropic dynamic effects of every crack.
