	abstract = {We present an implementation of a fully variational formulation of an
 immersed methods for fluid-structure interaction problems based on the finite
 element method. While typical implementation of immersed methods are
 characterized by the use of approximate Dirac delta distributions, fully
 variational formulations of the method do not require the use of said
 distributions. In our implementation the immersed solid is general in the sense
 that it is not required to have the same mass density and the same viscous
 response as the surrounding fluid. We assume that the immersed solid can be
 either viscoelastic of differential type or hyperelastic. Here we focus on the
 validation of the method via various benchmarks for fluid-structure interaction
 numerical schemes. This is the first time that the interaction of purely
 elastic compressible solids and an incompressible fluid is approached via an
 immersed method allowing a direct comparison with established benchmarks.},
