Modelling an undersea explosion

When determining the dimensions of naval defence equipment, it is difficult to conduct explosion tests on real structures such as ships and submarines. It is therefore necessary to model the damage caused by an undersea explosion.

The goal of the MESMA project is to develop a predictive model to quantify the effects of an undersea explosion on a structure and devise adequate protection.

By identifying the phenomena that take place during an undersea explosion, we were able to model the propagation of a pressure wave in the water and the resulting fluid/structure interactions. The results of the simulations were validated by correlating them with experimental data.
