Wave propagation,-d problems analytical or semi-analytical solutions exist. These solutions are used to either control numerical methods or also to study some basic effects of wave propagation. In this chapter, first, wave propagation in a poroelastic 1-d column is examined, followed by 3-d calculations using the proposed boundary element formulations.

Time domain boundary element formulation,In Chap. 3 the wave propagation in a beam, a one-dimensional continuum, was treated. Now, in this chapter the integral equation and, finally, a boundary element formulation for a two- (2-d) or three-dimensional (3-d) continuum will be deduced.

Indigence

Convolution quadrature method, to an arbitrary time-dependent load if the impulse response function is known. The convolution between the impulse response function and the loading is the solution. Other examples of convolution integrals are integral equations in time domain for elastodynamics or the hereditary integral formulation of viscoelastic constitutive equations.
