CALCULATION OF STRUCTURALLY INHOMOGENEOUS, PARTIALLY FILLED WITH LIQUID, SHELL DESIGNS.
A method for solving the static problems of multi-connected structurally heterogeneous shell structures, which are an arbitrary composition of multilayer shells, is proposed in the paper. Equations of equilibrium are obtained on the basis of the Lagrange variation principle. As an example, the matrix of complex stiffness values for a four-layer rectangular plate with different number of points of orthogonalization is calculated.
