Simulation of ultrasonic Non Destructive Testing (NDT) is helpful for evaluating performances of inspection techniques and requires the modeling of waves scattered by defects. Two classical flaw scattering models have been previously usually employed and evaluated to deal with inspection of planar or multifaceted defects, the Kirchhoff approximation (KA) for simulating reflection and the Geometrical Theory of Diffraction (GTD) for simulating diffraction. The student will theoretically study existing modified versions of the two previous approximations to deal with rough defects. These two methods will then be implemented, numerically evaluated, and compared with each other and with a reference numerical method.
