Abstract
In the present chapter a description of a finite element model of the heat transfer processes during pulsed and pulse phase thermography (PT and PPT) has been created using Ansys. The model is aimed at determining the heat transfer process through a realistic defect, understanding the effect of the system and material parameters as well as being a predictive tool. The aim of the predictive tool is to determine the thresholds of defect detection, as well as optimising the experimental parameters, such as pulse duration, for a particular joint of interest. The experimental procedures for PT and PPT are identical so the modelling approach is able to recreate the experimental conditions and parameters used for both. The results obtained from the model are then compared to the PT results in each case. PPT phase result may then be created by processing the modelled PT results.
