Numerical evaluation of effective material properties of randomly distributed short cylindrical fibre composites

The aim of presenting this paper is to evaluate the effective material properties of randomly distributed short fibre (RDSF) and transversely randomly distributed short fibre (TRDSF) composites with change in volume fraction, and aspect ratio of fibres. A numerical homogenization technique based on the finite element method (FEM) is used to evaluate the effective material properties with periodic boundary conditions. A modified random sequential adsorption algorithm (RSA) is applied to generate the three-dimensional unite cell models of randomly distributed short cylindrical fibre composites. The developed numerical homogenization technique is used to calculate effective material properties in order to systematically evaluate different material systems. The numerical results are also compared and verified with different analytical methods.
