Abstract

We have prepared this brief report to stimulate interest in and draw attention to a general concept we believe to be of considerable practical use in the determination of the strength, stiffness, and life (what we collectively call the material's response) of composite laminates. The general concept is the determination of stress redistribution during damage development. While the idea of stress redistribution is certainly not new, the suggestion that a general rational approach to the understanding and analysis of damage states and their effect on the materials response of composite laminates is both new and incompletely developed at this point. It is appropriate, then, that the generality and utility of this scheme be brought to the attention of the composites community by this communication so that a greater number of investigators can participate in the development of the concept if they wish. Less general but more specific and precise treatments of this subject will appear in the formal literature in the coming months.
