The paper presents the results of computer simulation and experimental investigation of blast wave action arising from a small explosive charge on a metal pyramid with a square base. This explicit finite element has been used to perform numerical analyses. This method is included in the Ls-Dyna software for modelling the behaviour of the pyramid exposed to the action of a pressure wave arising from the detonation of an explosive charge. The detonation process was described in programming bubble structure interaction was used to describe an influence of a blast wave on the structure.
