Cellular Rod with Varying Cross-Section under Impact

Abstract:

The aim of this paper is to investigate the effect of the gradient on the cross-section on the dynamic behavior of the graded cellular rods under impact loading. A graded cellular rod, whose cross-section varies along the axial direction, is supposed to impinged by a rigid mass G with initial velocity . The shock theory proposed by Reid and Peng [1] is employed to establish the analytical model. Similar to the previous work [2], the analytical results show that only one shock front appears when the gradient is positive while two shock fronts exist in the rod with negative gradient. Closed form solution is found for the single shock (SS) mode, while finite difference method is employed to obtain solutions for the double shock (DS) mode.
