Abstract

The paper presents the computational problems of application of the spatial finite element method for the calculation of constructions made of fiber-reinforced composites. Construction of stiffness matrix of a 3-dimentional finite element is performed taking into account the fibers’ spatial orientation. The moment scheme of the finite element is applied for improving results convergence. It is based on double approximation of displacement fields and deformation components and retaining some number of addends according to the definite rule. This approach is applied to the deformation problem of a hollow cylinder made of composite material. Numerical calculation results have shown good matching with analytical solutions.
