A Multiaxial Failure Criterion for Composites
Abstract
This paper presents the development of a piecewise quadratic strength tensor theory for composites with orthotropic, transversely isotropic, and isotropic material symmetries. The proposed failure criterion improves the best available quadratic failure theory for such composites, the Tsai and Wu quadratic strength tensor theory, by including stress terms that can reflect different failure mechanisms of the composites under tension and compression. To demonstrate the applicability of the proposed theory to composites, extensive and good correlations are shown between the theory and the biaxial fracture data of five composite material systems: graphite epoxy, graphite particulate, graphite aluminum, glass epoxy, and organic textolite composites. Isotropic, Quadratic strength, Orthotropic.
