We consider the inverse problem of determining the Lame parameters and the density of a three-dimensional elastic body from the local time-harmonic Dirichlet-to-Neumann map. We prove uniqueness and Lipschitz stability of this inverse problem when the Lame parameters and the density are assumed to be piecewise constant on a given domain partition.
