The objective of this study is to locate damage to the fiber matrix interface of composite material by the nonlinear acoustic technical, which is commonly described by the addition of a nonlinear term in the Hooke’s law. Genetic simulation is essentially based on the probabilistic Weibull model including nonlinear parameter. Results obtained show good agreement between the numerical simulation and the actual behavior of two materials carbon epoxy (T300/914) and polyetheretherketone (PEEK/APC2) on the one hand, and second they are similar to the results obtained by the analytical model based on the Cox and Weibull formalism. However, it would be interesting to extend this study on hybrid composites and nanocomposites.
