The Head-On Collision of Normal Shock Waves with a Concrete Supported Plate

Abstract

The process of normal shock wave collision with a concrete wall is of considerable importance from both the theoretical and engineering points of view. The ability to predict the overall picture of the stress field for a concrete wall of prescribed physical properties, exposed to shock waves, is important for designing the walls. The numerical simulation of shock wave collision, reflection and transmission may also contribute to the investigation of concrete wall behaviour in the compressed state. From an industrial standpoint, it is necessary to estimate the minimal width and mechanical properties of the concrete wall that can withstand shock waves of given intensity. Such information is vital for designing protective shielding for people, as well as civil and military structures. The numerical scheme and the computer code for the shock wave propagation and interaction problem have been developed in the context of the present investigation.
