Název v původním jazyce

Overall Viscoelastic Response of Random Fibrous Composites with Statistically Quasi Uniform Distribution of Reinforcements

Popis výsledku v původním jazyce

An accurate representation of time dependent response of polymeric composite systems with disordered microstructure is developed within the framework of classical homogenization methods. The investigation is focused on modeling issues pertinent to random, non-periodic, material systems, while the loading conditions are left to those promoting the linear viscoelastic deformation only. Two different approaches are examined. The first approach assumes a well defined geometry of the fiber arrangement and specific boundary conditions. In the modeling framework, the complicated real microstructure is replaced by a material representative volume element consisting of a small number of particles, which statistically resembles the real microstructure. Periodicdistribution of such unit cells is considered and the finite element method is called to carry out the numerical computation. The theoretical basis for the second approach are the Hashin-Shtrikman variational principles
