The principle of hidden corrosion detection by Pulsed Infrared Thermography is based on the analysis of spatial-temporal phenomena which occur in corroded sites subjected to stimulated heat diffusion. In this paper a heat transfer model, based on the Finite Element Method (FEM), is used to solve the inverse problem. The goal is retrieving the whole corroded profile instead of estimating the corrosion level in the middle of a defect. The proposed method is based on an iterative deformation of the mesh. Numerical and experimental results of a 2D case study will be reported.

Abstract
The principle of hidden corrosion detection by Pulsed Infrared Thermography is based on the analysis of spatial-temporal phenomena which occur in corroded sites subjected to stimulated heat diffusion. In this paper a heat transfer model, based on the Finite Element Method (FEM), is used to solve the inverse problem. The goal is retrieving the whole corroded profile instead of estimating the corrosion level in the middle of a defect. The proposed method is based on an iterative deformation of the mesh. Numerical and experimental results of a 2D case study will be reported.
