This paper is devoted to studying impedance eigenvalues (that is, of a particular Dirichlet-to-Neumann map) for the time harmonic linear elastic wave problem, and their potential use as target-signatures fluid-solid interaction problems. We first consider several possible families elasticity focusing on certain that are an analogue Steklov eigenvalues. show one these arises naturally in inverse...

In this contribution we introduce a novel space-time formulation for non-linear elasticity, able to calculate large deformations and displacements with high efficiency using structured unstructured meshes in the cylinder without changing required regularity thus, enabling use of Lagrangian shape functions including tetrahedron hypertetrahedron or tesseract elements. The common indiscriminate tr...
