Semi-analytical finite elements methods for dispersion curves using higher order elements for long range ultrasonic testing

Guided waves have great potential as a NDE method. For this purposes it is very important to obtain the dispersion curves which depend on the cross-section of the structures in the guide waves. For the case of an arbitrary cross-section semi analytical finite element methods are developed. This paper describes the use of different node elements in the performance of the SAFEM algorithm using high order elements.
