| Abstract |
The construction of a shell model for layer-by-layer stress–strain analysis of irregular sandwich shells of revolution of double curvature is considered. The construction of the model is carried
out on the basis of the block finite element (FE) approach. In so doing, two types of shell finite elements (FE) of double curvature are considered – a two-dimensional FE of the bearing layers and a
three-dimensional FE of the filler. A comparative analysis of the calculation results based on the given
algorithms using finite elements of bearing layers with analytical and finite element solutions obtained
using the ANSYS software package on the problem of deformation of a single-layer spherical shell
under the action of self-balanced forces is carried out. As an example, the problem of studying the
influence of through and blind rectangular cutouts on the stress–strain state of a doubly curved sandwich shell of revolution is solved. |
