Nondestructive Evaluation Using Topological Derivatives for Materials with Voids and Cracks

Abstract

A determination of voids and cracks in materials simultaneously using topological derivatives is considered. We determined voids using topological derivatives for voids and determined cracks using topological derivatives for cracks in our previous studies. In this study, we determined both voids and cracks in materials simultaneously using topological derivatives for voids and their gradients in a simple problem.
