Basic formulas
$4{\alpha }^4=\frac{\overline{D}}{4{\lambda }_z}$; ${\beta }^2=\frac{{\lambda }_x}{{\kappa }_s}$.
$D_i=\frac{E_i{h}_i{}^3}{12}$(plane stress); $\overline{D}=\frac{1}{D_1}+\frac{1}{D_2}$.
${\kappa }_s={\kappa }_{s1}+{\kappa }_{s2}+{\kappa }_{\mathrm{s}3}$
${\kappa }_{si}\approx \frac{h_i}{8G_i},i=1,2;{\kappa }_{s3}=\frac{h_3}{G_3}$
${\lambda }_x={\lambda }_{x1}+{\lambda }_{x2}+{\lambda }_{x\theta }$
${\lambda }_{xi}=\frac{1}{E_i{h}_i},i=1,2;{\lambda }_{\mathrm{x}\theta }=\frac{1}{4}\left[\frac{h_1\left(h_1+h_3\right)}{D_1}+\frac{h_2\left(h_2+h_3\right)}{D_2}\right]$
${\lambda }_z={\lambda }_{z1}+{\lambda }_{z2}+{\lambda }_{\mathrm{z}3}$
${\lambda }_{zi}\approx \frac{13}{32}\frac{h_i}{E_i},i=1,2;{\lambda }_{z3}=\frac{h_3}{E_3}$
${\mu }_{\sigma }=\frac{1}{2}\left(\frac{h_2}{D_2}-\frac{h_1}{D_1}\right),{\mu }_{\tau }=\frac{1}{2}\left(\frac{h_2+h_3}{D_2}-\frac{h_1+h_3}{D_1}\right)$
