On the Uniqueness of Singular Solutions to Boundary-Initial Value Problems in Linear Elastodynamics.

Abstract

The classical uniqueness theorem for the traction problem in the linearized dynamical theory of possibly non-homogeneous and anisotropic elastic solids has been generalized to encompass problems whose solutions exhibit suitably restricted stress-singularities. The types of singularities covered by the theorems obtained here include finite jump discontinuities in stress, which are familiar from known solutions to dynamical elasticity problems involving discontinuous data or non-matching boundary and initial conditions. In addition, one of the theorems established accommodates square-integrable isolated stress-infinites, such as those arising in connection with the focusing of elastic waves. (Author)
