Abstract

In this chapter, we describe the Hybrid Displacement Boundary Element Method for the time domain and derive formulations for elastodynamics and acoustics. These formulations lead to symmetric systems of equations with time-invariant mass and stiffness matrices. The symmetry is exploited to formulate a symmetric coupled system of equations for fluid-structure interaction in time domain.
