Abstract : Develop the piecewise quadratic strength tensor theory for composite materials and demonstrate its applicability to the available biaxial fracture data on composites. The theory will have application to current composite structures of Naval Ocean Systems Center's interest such as transducers and future composite structures such as torpedo hull section, Vertical Launch ASROC (VLA) nosecaps, and tethered deep submergence structures. The theory can also be used with a wide variety of other NAVY structures such as aircraft and submarine substructures. Keywords: Multiaxial failure theory, Composite strength, Strength tensor theory, Orthotropic material, Transversely isotropic material, Graphite/Epoxy, Glass/Epoxy, Graphite/Aluminum, Graphite particulate.
