Abstract

Ultrasonic nondestructive testing is a widely used method for searching for defects, e.g. cracks, in the nuclear power industry. Even though the method can be considered as wellestablished the theoretical understanding is far from complete, especially when more complicated situations are considered. Consequently, it is advantageous to have access to a good mathematical model of the testing procedure. Such a model can, for instance, be used to perform parametric studies, to develop testing procedures, for qualification purposes, and for education. Furthermore, systematic use of a well tested and validated simulation program will most likely result in a better physical understanding of the process. It should also be emphasized that experimental work is a very expensive alternative to mathematical modeling.
