heal.abstract	The failure strengths of anisotropic bodies and especially those of fiber reinforced materials are generally studied at the principal directions of their strength and loading of the bodies. For the most reliable criteria, based on failure functions having the form of a general tensorial polynomial, the modes of failure of anisotropic (orthotropic, transversely isotropic) bodies were studied primarily on the principal stress (sigma-1, sigma-2, sigma-3)-subspace. The elliptic paraboloid failure surface, (EPFS), being one of them, was based on the phenomenological assumption that even the anisotropic media do not fail under the influence of any hydrostatic pressure superimposed with an elementary loading, taking care of the anisotropy. Modes of failure of orthotropic media under the influence of shear loading, which are very important especially for the transfer of loading between fibers and matrix in a single lamina, as well as in the theory of failure of laminates, was up-to-now neglected. In this paper the effect of shear is studied for transversely isotropic and orthotropic materials. The dependence of the pure shear loading on the sign of shear, as well as on the parameters of anisotropy of the medium, is established. Interesting results are revealed, having a direct application on a well-founded theory of strength of laminates.	en
