A theory employing the tensor functions representation is outlined. Experimental data regarding deformation modes, volume changes and yielding are presented. Anisotropic deformation of a stratified rock (diatomite) subjected to a sequence of isotropic pressures is demonstrated in the permanent deformation range. Originally circular cylindrical specimens are shown to deform to elliptic inclined cylinders depending on the orientation of privileged directions of anisotropy to the cylinder generator. Experiments disclose essential features of mechanical anisotropy in the irreversible deformation range. Affiliations:
