Partial corrosion shape identification analysis around reinforcement bar for three dimensional reinforcement concrete model using practical observed temperature on concrete surface

Abstract

This paper describes partial corrosion shape identification analysis around reinforcement bar for three-dimensional reinforcement concrete model using practical observed temperature on concrete surface. The heat transfer analysis and the corrosion shape identification analysis are respectively performed by the finite element method and the adjoint variable method. In this study, we focus on the thermal testing in the nondestructive testing methods, and the corrosion shape identification analysis is carried out by the observed temperature on concrete surface.
