Paper reviewed laminate failure occurred under tri axial loadings by using macromechanical based failure theories applied under static loading conditions. The proposed failure model by various authors is an extension of the strain energy failure theory for tri axial loading conditions. The paper summarizes laminate failure which includes initial failure, progressive damage, and final failure different laminate ply and material configurations. The paper also reviewed the structure failure due to stress concentration effects arrive due to edging effects. The aim of paper is to present failure of complex composite laminate by various means due to complex loading conditions much similar to actual operational loadings.
