Finite Element Model of Laminated Shells of Composite Materials

Finite element models of fiber-reinforced polymer composite elements as a characteristic part of layered structures are considered in order to adapt them to the developed method of calculations of structural elements as multilayered orthotropic bodies and to compare the obtained results with the experimental ones. The problem is solved numerically and analytically using the finite-element method. Finite element meshes of models are constructed by the adaptive method with the introduction of small additional elements in the critical zones in each cycle of the computational analysis. The complex structure of multilayer composite materials is taken into account. The physical and mechanical characteristics of composite materials obtained by experimental studies on samples made by autoclave molding and thermo-vacuum method according to international standards are used.
