4. Appendix A: Plate vibration
4.1 Propagation wave velocity in solids
In a solid, the coefficient of proportionality between stress and strain is an elasticity constant, usually expressed in N/m 2 .
We distinguish :
longitudinal modulus of elasticity or Young's modulus E (N/m 2 ) ;
transverse modulus of elasticity or modulus of rigidity G (N/m 2 ).
For all materials, there is a relationship between E and G defined by the Poisson's ratio:
