Abstract
This paper deals with the highly nonlinear shock-wave phenomena in reinforced concrete multi-shock shields (CMS). The shock-waves arise from the contact-detonation of a TNT explosive charge. The response of concrete under high solid compression up to 15 GPa is of great interest for the design of containment structures to resist accidental explosions or catastrophic collisions. A novel approach is presented to model reinforced concrete under shock-wave loading and attempt to predict brittle damage modes. The paper outlines the material and numerical aspects for modelling shock-wave phenomena. Computational applications confirm the validity of the proposed formulation.
