• This paper presents the results of an investigation carried out into the plastic collapse and deformation behaviour of a rotating pipe impact on a stationary target pipe. To predict the plastic energy dissipation during the deformation of circular section pipes, a modified plastic collapse analysis adapting upper bound technique based on an existing deformation mechanism model was considered. The studies carried out show clearly that the failure mode in a pipe during impact with another pipe or with a solid rod does not only depend on relative local strength of these pipes but is due to a complex interaction of various parameters, e.g. impact velocity, span to diameter ratio of the target pipe and the supporting conditions of the target pipe and also of the impact position. The results throw good light and illustrate the influence of kinetic energy and its impact position on the energy absorption characteristic of the target pipe.
