A Mathematical Analysis of the Strip-Element Method for the Computation of Dispersion Curves of Guided Waves in Anisotropic Layered Media

Figure 3

Components of the displacement vector $u=(u_x,u_y,u_z)$ over the thickness of the plate at $\varphi =70^{\circ }$ of $S_0$- and $S{H}_1$-modes for different ratios $E_2/E_1$. Here $u_x$ and $u_y$ are the in-plane components in longitudinal and transversal directions, respectively. Obviously the distinction between shear-horizontal and in-plane Lamb-waves becomes less clear in an anisotropic material. This means especially that common measuring techniques quantifying the $z$ component will detect also the $SH$-modes.
