ABSTRACT
In this paper we study numerical modelling of Lamb waves propagation and its interaction with delamination in orthotropic plate. Firstly a theoretical model is established to obtain the equation of lamb modes propagation. Secondly dispersion curves are plotted using Matlab program for the laminate [0]4. The simulations were then carried out using ABAQUS CAE by exciting the fundamental A0 Lamb mode in the frequency 225 kHz. The reflection is finally investigated in the case of asymmetric delamination.
