Section 4: Elastic Properties
A solution if the wave equation has the form of a propagating longitudinal plane wave u(x,t) =Aei(qx−ωt) xˆ , (4.23) where q is the wave vector, ω=vLq , is the frequency, and (4.24) v 11 L C ρ = (4.25) is the longitudinal velocity of sound. (2) Now we consider a transverse wave which is controlled by shear stress and strain. In this case ...
