DESCRIPTION:Stephanie Chaillat\, Laboratoire POems\, École Nationale Supéri
 eure de Techniques Avancées Paris\n\nFast Boundary Element Methods to simul
 ate underwater explosions and their interactions with submarines\n\nAssessi
 ng the impact of underwater explosions on submerged structures (submarines)
  is an important naval engineering problem. An underwater explosion mainly 
 induces two distinct phenomena: a "shock wave" followed by an oscillating b
 ubble of gas. Our goal is to create an efficient numerical method that acco
 unts for the effects of both phenomena on submerged structures. Due to the 
 unbounded nature of the ocean and the complex mechanical behavior of the su
 bmarine we want to take into account\, it is natural to consider a Boundary
  Element Method/Finite Element Method (BEM/FEM) coupling. I will present ho
 w we can take advantage of fast BEMs in the frequency domain to model this 
 time-domain problem\, all the necessary improvements to be able to consider
  realistic configurations and the consequences on the convergence of the FE
 M/BEM coupling.
