Abstract

The application of composite materials in different areas of industry leads to the need of inspection of such components. One of the inspection techniques which are already used is based on the ultrasonic guided waves. However, modelling of guided waves propagation in composite components meets multiple problems: geometrical and structural complexity of components, anisotropy of materials, not defined elastic properties. This leads to the fact that the modelling task cannot be solved using only one simulation technique. So, the objective of the investigations carried out was to review analytical and semi-analytic modelling methods related to propagation of ultrasonic guided waves and to define which question can be answered by them.
