The objective of this paper is to study the location of the shear damage to the fiber matrix interface of a hybrid composite material by using the nonlinear acoustic technique, which is commonly described by the addition of a non-linear term in Hooke’s law. The genetic simulation is based on the probabilistic Weibull model including non-linear parameter β. The results obtained show good agreement between the numerical simulation and the actual behavior of two hybrid composite materials: alfa-carbon/Epoxy and glass-carbon/ Epoxy. In addition the results are similar to those obtained by the analytical model, which based on the Cox and Weibull formalism. The extended study for nanocomposite materials is interesting in the future.
