Abstract
This paper deals with the inverse problem of detecting the level of corrosion at the interface of an inclusion given thermal measurements at the accessible boundary of the sample. This leads to a transmission problem for the heat equation with an unknown coefficient in a transmission condition. We consider both time-harmonic and delta-pulse excitations. In both cases we prove uniqueness results for the inverse problem. To reconstruct the unknown level of corrosion numerically, we study a non-iterative method and a regularized Newton method and compare their performances in a number of numerical experiments.
