Modeling of surfaces of composite strength on the basis of the microstructural finite element analysis
Engineering Education # 11, November 2012
DOI: 10.7463/1112.0496336
In this work a method of microstructural finite element analysis for calculation of strength surface of composite materials with periodic fabric structure of reinforcement on the basis of a developed software was proposed. This method is a method of asymptotic averaging adapted for multi-scale periodic structures developed by Prof. Y. Dimitrienko at the "Computational Mathematics and Mathematical Physics" department. The method is based on solving a special class of elasticity problems on 1/8th of the periodicity cell of the composite in order to determine effective elastic properties of the material. The results of calculation of ultimate strength for disperse reinforced and textile composites are presented.
