A micromechanical model for a Representative Volume Element (RVE) of a composite material to study the interface adhesion is introduced. The composite constituents assumed to have elastic properties with unidirectional fiber arrangement. The characterization is performed to study the interface and the separation/delamination of layers and their impacts on the overall mechanical response and properties of the composite material. Finite element package ANSYS is used to simulate the conditions of the interface employing cohesive zone modeling. The impact of an increasing axial transverse loading force on the interface in terms of its separation is studied. The exponential traction-separation curve pioneered by Xu and Needleman [1] will be implemented. The RVE is periodically constrained to represent a common element within the continuum domain far from the locality influence of the force and for a homogenized mechanical behavior study of the interface. The examination of the characteristics of the cohesive zone element as a simulation tool for interface analysis gives us conditions of a closer simulation for tissue engineering analysis.
