Abstract : Based upon considerations relating to the nature of the interlaminar stresses in composite laminates, an approach is presented to predict the detailed stacking sequence of specific layer orientations which leads to optimum protection against delamination under uniaxial static and fatigue loadings. It is argued that the interlaminar normal stress, as well as the interlaminar shear stress, is instrumental in precipatating delamination and subsequent strength degradation. Correlation with existing experimental evidence of the stacking sequence phenomenon is presented. (Author-PL)
