Numerical Simulation of Masonry Wall under Explosive Load inside

Abstract

The explosion process of masonry wall under interior explosive load was simulated by adopting the fluid-solid coupling method basing on the software ANSYS/LS-DYNA. The Von Mises stress nephograms and the contrast analysis of the numerical simulation results and test results were presented. The research indicates that mortar elements fails earlier than brick, a little difference exists between the sizes of the blasting hole in X and Y direction because of the transmission of blast wave in brick masonry, the size of blasting hole grows with the increase of weight of charge, and with the increasing charge, the rate of change declined gradually.
