Abstract
In this paper, dynamic compression response of metal orthogonal corrugated sandwich structures under impact loading is investigated theoretically and numerically. Considering the effect of strain rate of material, analytical models of dynamic response of metal orthogonal corrugated sandwich structure is developed. Finite element simulation of its dynamic compressive response is carried out. It is shown that there is a good agreement between the results based on the analytical model and finite element simulation. Furthermore, the dynamic compressive response of multi-layer orthogonal corrugated sandwich structure is studied using finite element method. Deformation modes under different impact velocities are obtained and the influence of the number of layers on the dynamic response is analyzed. It is found that the mitigation and energy absorption capacity of the sandwich structures can be effectively enhanced by increasing the number of layers while the number of layers have mild influence after exceeding four.
