The use of simulation in the development of ultrasonic testing

The report focuses on the principles of modelling the ultrasonic inspection, the possibilities of modelling and the its limitations. Some of the existing models have been extensively validated and are in routine use. Efforts has also been put on modelling the inspection of anisotropic media, such as austenitic welds, but these models presuppose that the texture of the weld is known and this is usually not the case in practice. This fact restricts the usefulness of modelling to a more qualitative description of the beam bending phenomena in the case of austenitic welds
