Damage and deformation growth in brittle-ductile laminates

An analysis describing the behavior of a brittle ductile laminated system is performed in this work. The brittle and the ductile materials are in the form of alternating thin layers to form multimaterial laminated system. The brittle material is stiff, while the ″ductile″ material, which serves as the reinforcement, is strong and has larger strain to failure. The theoretical analysis suggested here is based on a one dimensional shear-lag theory, combined with elastic-perfectly plastic behavior of the interface. A comparison between the current theory and others reveals the potential of this theory. The theory predicts the mechanical behavior of an alumina carbon/epoxy laminated system.
