Abstract

The finite-element model for calculation of stressed-strained state of momentum bearing layers of three-layered conic shells is considered. Into approximation functions of displacements of finite elements of bearing layers are included displacements as hard whole (determinated by integration of proportions of Koshi at zero values of deformation) which leads to increasing of convergence speed of numerical results.

Keywords:

finite element, stressed-strained state, bearing layers, three-layered conic shells, approximation functions, displacements as hard whole, proportions of Koshi.
