Abstract
Due to the fact that traditional rock constitutive models are constructed under static loading conditions and cannot accurately describe the mechanical behavior of rocks under dynamic loading, it is of great theoretical value to study the dynamic constitutive theory exhibited by layered shale under impact loading. This article constructs a dynamic damage constitutive theory for layered shale based on the dynamic mechanical deformation and failure characteristics exhibited by shale with different bedding dip angles in impact loading experiments. Based on this theoretical model, a program of the finite element method was developed to numerically simulate the impact test process of layered shale. The results indicate that the finite element program developed based on the dynamic damage constitutive model in this article can effectively reflect the dynamic mechanical characteristics of layered shale during impact loading.
