A technology of simulating the structure deformation process by expanding the structural finite elements (shell and beam elements) to obtain solid elements of continuum (hexahedrons, triangular prisms) has been developed and implemented in the static strength module of the LOGOS code package. This technology allows simulating the nonlinear deformation of thin-walled structures with shell and beam elements owing to the earlier implemented capabilities for solid elements. The basic procedures and algorithms of the implemented method are described, results of test simulations of nonlinear problems with regard to geometrical nonlinearity are presented and compared with the available benchmark solutions. Keywords: LOGOS code package, static strength, the finite element method, nonlinear straining, the solid-shell technology.
