Determination of Young modulus by using Rayleigh waves

Abstract

The aim of this work is to provide a non-destructive testing technique to obtain the physical properties of a given material, based on a series of images, obtained through a non-invasive procedure, that capture the experimental propagation of a Rayleigh waves packet travelling through it, and allowing us to obtain the phase velocity of the waves packet. The proposed procedure involves a minimization technique that requires the numerical simulation of the travelling waves to obtain the optimal material parameters. Numerical results are compared with experimental data to validate the procedure.
