Numerical-Experimental Investigation of Squared-Based Metal Pyramids Loaded with A Blast Wave From A Small Explosives Charge

The paper presents the results of computer simulation and experimental investigation of blast wave action arising from a sma explosive charge on a metal pyramid with a square base. This method is included in the Ls-Dyna software for modelling the behaviour of the pyramid exposed to the action of a pressure wave ari ing from the detonation of an explosive charge. The detonation process was described in programming bu structure interaction was used to describe an influence of a blast wave on the structure. Key: FEM, Blast Wave, Blast Wave Interaction
