Multiscale modeling of composite materials has become quite popular for analysis of composite structures. Progressive failure analysis of composites is one area where micromechanics based approaches are widely used. Micromechanics approach requires the modeling of the smallest repetitive volume, also called as the Representative Volume Element (RVE), such that volume fraction of the RVE must be in accordance with the volume fraction of the composite material. Current study aims to show both 2D and 3D RVE applications through a complete homogenization process of the 3D model of the unidirectional composite material. Comparisons of the elastic moduli determined by the 2D and 3D RVEs are formed and compared. The applicability of the 2D RVE in micromechanics analysis of a 3D macro structure is investigated.
