heal.abstract	The advent of new fiber composite materials rendered indispensable the remodeling of the existing yield criteria, which were based on simplifications like the continuing general isotropy of the material during loading and the absence of any strength differential effect. It was shown in this paper that all anisotropic materials obey a general type of failure criterion having the shape of an elliptic paraboloid, conveniently oriented. This yield locus degenerates into a paraboloid of revolution for isotropic materials having the hydrostatic axis in the principal stress space as axis of symmetry. For transversely isotropic materials the paraboloid of revolution becomes an elliptic paraboloid surface, whose axis of symmetry is parallelly displaced from its initial position of the isotropy. Important features of this criteria check satisfactorily with experimental evidence.	en
