Abstract
IN rheology we study the development in space and time of the mechanical variables, that is, of the stresses and strains which co-exist in a material in every differential cell, and at every instant. Our concern here will be the comparison between different directions in space, and we shall speak with respect to any quantity, or development, of isotropic symmetry to denote identity in the various directions, and of anisotropic symmetry to denote differences from one direction to another.
