A time domain harmonic BEM implementation for non-homogeneous 3D solids

In the present work, a Boundary Element Method implementation is presented for a specific non-homogeneous elastic media. The media under consideration is a Poisson solid (ν=0.25), which requires additionally a quadratic variation for the material parameters along one cartesian axis (e.g. depth). The 3D problem for the time-harmonic case was implemented and numerically validated for specific problems. Moreover, the static version of the present problem was used to model a real functionally graded composite of alumina–nickel.
