Modeling and optimization of open crack detection by active thermography

Abstract

The aim of the presented work is the detection of open defects in metallic materials using laser-material interaction coupled with infrared thermal images. This process is a possible alternative for magnetic particles testing and penetrant testing in the field of non-destructive testing. In this context, a numerical simulation model is implemented with Comsol Multiphysics®. This model allows us to look for the process optimal parameters through numerical experimental designs.
