A Survey of Failure Theories of Isotropic and Anisotropic Materials

Abstract : A survey of various theories of strength for isotropic and anisotropic materials is presented. For anisotropic materials theories of failure are broadly classified as theories with or without distinct failure modes. The former class includes the criteria based upon maximum stress and strain while the latter are quadratic or biquadratic representatives in which the transition from one failure mode to another is gradual.
