Thermal non-destructive evaluation (TNDE) techniques based on IR Thermography have becoming a mature method for the aerospace industry. For the development of new procedures, the optimisation of the experimental set-up and the assessment of the inversion algorithms that are used by TNDE techniques, reference data are required, which can be provided by simulating the thermal behaviour of the inspected structures.In this work, the computerised simulation of thermographic inspection procedures by mathematical methods is investigated. The analysis is focused on the modelling strategies that can be implemented by means of commercial software packages to solve numerically the heat conduction problem in composite structures. When affordable, exact analytical solution of the heat diffusion originating during the testing procedures is reviewed as well.
