Summary

This is the final report of a three-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The ability to design composite materials and analyze processing procedures relies on the availability of constitutive models that describe their dynamic response accurately. The strength, damage evolution, and failure of interfaces within composites often dominate their macroscopic performance but are not well characterized. The design of such composites for particular applications requires adequate knowledge of interfacial characteristics. Given the large number of potential loading scenarios that an engineering composite can be subjected to, it is obviously beneficial to have reliable and accurate theoretical methods for their quantitative treatment in numerical calculation. This project addresses the fundamental aspects of interfacial debonding in composites, and examines the basic behavior in practical situations.
