Finite element/boundary element coupling for airbag deployment

Fluid–structure interaction of inflatables comprizes a family of applications, of which airbags are one. Challenges in this domain are complex geometries requiring relatively high resolution; large displacements possibly entailing severe mesh distortion; and strong coupling. A promising approach seems to be coupling a classical finite element formulation for the airbag fabric to a boundary element formulation for the enclosed fluid. Together with an appropriate time-integration scheme this method answers aforementioned challenges, as demonstrated by numerical simulation.
