heal.abstract	The elliptic paraboloid failure surface has been well established as a potential criterion for yielding and failure of transversely isotropic materials, presenting also the strength differential effect [1]. This was done by extending well established criteria for isotropic materials presenting the strength differential effect (SDE), through an introduction process which maintained basic physical principles for the anisotropic materials. All previous literature concerned the special case where the principal axes of the external loading coincided with the principal strength axes of the material. In this paper the most general case where the two systems of frames are arbitrarily oriented relatively to each other is considered. In this situation the simplifications derived from the coincidence of the external principal stress and material principal strength axes are lost and the material should be considered as a general orthotropic one. The general properties for such types of loading of the transversely isotropic material are established by maintaining the general features of the failure locus invariant. Then, this study completes the investigation of yielding and failure mode of such materials considering the most general case of their loading. © 1989 Steinkopff.	en
