摘要

The aim of this work is to model the behavior of ultrasonic waves into multi-layered components. The propagation of the direct field transmitted through the inner interfaces is predicted by applying an homogenization approach, in which the parallel layers are replaced by a homogeneous material with the proper stiffness constants. The noise due to inner reflections or interaction with porosities is modeled in a second part by means of a statistical approach.
