Wave propagation across a finite heterogeneous interphase modeled as an interface with material properties

摘要

Highlights ? An identification procedure for a surface with material properties replacing a finite heterogeneous interphase is proposed. ? The results are compared with finite element simulations. ? The validity range of the model is defined and highlighted. ? The importance of the inertial properties of the interface is shown. Abstract Mechanical problems involving an interphase between two well-defined, and eventually different, materials are of interest. The aim of this paper is to pres
