Abstract

The concern of this paper is the study of the effects on a thick concrete wall of the detonation produced by an underwater explosive device, in close range. This work applies in particular to the study of some industrial pools, filled with water and a few meters deep. These pools are generally build so as to ensure a certain watertightness, this function being obtained for instance by covering the internal surface with an internal liner, a few millimeters thick and made of stainless steel. Here, we focus on the possible loss of this function both by the damage caused to concrete and the perforation of the liner, due to the local effects of the explosion independently of the global structural response. In the paper, based on the Holmquist et al.[1] model for the behavior of concrete under high press
