Two idealized packing have been developed to carry out the analysis in finite element software package ABAQUS. Translational symmetric transformation has been applied to make the simplest model for the analysis which can save the time for the analysis. Appropriate periodic boundary conditions have been derived for both the packing by using uniform microscopic field. Unit cell obtained from this section can be subjected to arbitrary combination of the macroscopic strains and the response of the unit cell is observed to take out the effective material properties using the simple elasticity approach. Mathematical models are presented to obtain the values of the effective material properties so that they can compared with the numerical model. Further parametric study has been carried out to check the dependency of fiber and matrix on the overall effective material properties. More significant analysis has been done on effective material properties to make it useful for the selection of the appropriate material for the specific application
