Relationships that take geometric nonlinearity, transverse-shear deformation, and lack of inclination into account are derived. The principal directions of layer elasticity in multilayer plates and shells form a certain angle with the coordinate lines. The conditions of layer contact are satisfactory with respect to displacements. The three-dimensional problem is reduced to a two-dimensional one, The problems are solved by the finite-element method in displacements. The stiffness matrix and vectors of geometrically nonlinear terms for various shells as parts of a torus, cone, sphere and out-of-round cylinder are presented. The results are given in the form of diagrams. The stiffness matrix and vectors of geometrically nonlinear terms are derived for a N-angle element. Conversion from one form of shell to another is achieved by varying the quadratic-shape factors and their derivatives using subroutines for each type of shell. |
