This contribution presents a three dimensional constitutive model for anisotropic damage to describe the onset and propagation of ply failure mechanisms in unidirectional fiber reinforced laminated composites. The primary objective of the work focuses on the three dimensional relationship between damage of the material and the effective elastic properties for the purpose of stress analysis of composite structures. Damage initiation criteria are based on Puck failure criterion for first ply failure and progressive micro crack propagation is based on the idea of continuum damage evolution.
