abstract:
Basic static boundary value problems of elasticity are considered for a 
semi-infinite curvilinear prism $\Omega=\{\rho_0<\rho<\rho_1,$ 
$\alpha_0<\alpha<\alpha_1,$ $0<z<\infty\}$ in generalized
cylindrical coordinates $\rho,$ $\alpha$, $z$ with Lam\'{e} coefficients $h_\rho=h_\alpha=h(\rho,\alpha),$ 
$h_z=1$. It is proved that the solution of some boundary value problems of 
elasticity can be reduced to the sum of solutions of other boundary value 
problems of elasticity. Besides its cognitive significance, this fact also 
enables one to solve some non-classical elasticity problems.
