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.
