Description
This module aims to convey the basic physical principles of physical acoustics. The equations governing wave propagation in various media, both fluids and solids, are established. Depending on the geometry of the problem (infinite or bounded media), the solutions of these wave equations are examined, taking into account boundary conditions. Each case studied is illustrated by industrial applications.
Course outline:
Acoustic waves in fluids - Progressive, stationary and guided waves. - Equation of plane wave propagation. - Reflection/refraction of plane waves. - Spherical waves - Radiation. Elastic waves in solids - Propagation in infinite media. - Propagation in semi-infinite media (Rayleigh waves). - Propagation in bounded media (Lamb waves). - Applications to NDT.
