Numerical Evaluation of Effective Elastic Properties of Graphite Fibre Tow Impregnated by Polymer Matrix
Original language description
Homogenized elastic material properties are found for a fibrous graphite-epoxy composite system with fibers randomly distributed within a transverse plane section of the composite aggregate using the finite element method. To enhance efficiency of the numerical analysis the real microstructure is replaced by a material representative volume element, represented here by a periodic unit cell consisting of a small number of particles, which statistically resembles the actual composite. Such a unit cell isderived from a simple optimization procedure formulated in terms of various statistical descriptors characterizing the microstructure of the random medium. In the present approach the two-point probability and the second order intensity functions are employed. The upper bound on the macroscopic elastic stiffnesses then follows from the principle of minimum potential energy. The Finite Element Method (FEM) is called to carry out the numerical analysis.
