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.
