Composite materials have a widespread use in engineering applications and modern structures because of the qualified physical and mechanical properties. Therefore, study the structures of composite material becomes attractive and reserchers to obtain novel materials that qualified environment updates. In this study, the displacements and stress analysis of two-dimensional composite materials have different modulus of elasticity and mechanical properties have discussed. Finite difference method was used in this study where the model solved using Fortran 90. The results show that, the change in elasticity in one of the layers has significant effects on the displacements and stresses distributions of the layers of the composite. In addition, the influence of passion’s ratio with elasticity at the same time is discussed. They have important effect on the stress analysis. The results were in the acceptable limit which confirms the reliability of the finite difference method.
