摘      要：The elastic-plastic behavior and failure of pipe-on-pipe impact(p-o-p-i)problem is studied through analytical model and numerical simulation in this *** impact of a whipping pipe with one end hinged and the other end free on a simply-supported target pipe at its midpoint is *** analytical model based on tubular beam theory is proposed in the study of the deformation and plastic collapse behavior of pipes impacted on different positions and therefore to obtain the various failure modes depending on the material and structural parameters of the *** simulations using the finite element code MSC-Marc are performed and the results are coincident with the theoretical predictions.
