Comparative analysis of two approaches to more accurate calculation of laminate shells made of composite materials
- 22 Downloads
We worked out an approach based on the theory of multilayered anisotropic shells which makes it possible to investigate the state of stress and strain of structures made of composite materials and taking into account the local effect in the geometrically nonlinear statement.
We worked out an approach for calculating laminate anisotropic shells of revolution on the basis of the geometrically nonlinear theory of elasticity with numerical realization by the finite element method.
For the first time all the stress tensors calculated with a view to the geometrically nonlinear deformation of laminate shells of composite materials were compared with each other.
