| Abstract: | Dynamic equations for the penetration of a conical rod against semi infinite cement target are established by using the theorem of momentum and the law of kinetic energy.The impact force is determined by numerical solution of the nonlinear equations. Then according to Newton's second Law, the wave equation of the conical rod is established and the stress wave propagation in it is studied. |
