A class of univeral relations in isotropic elasticity theory
A class of universal relations for isotropic elastic materials is described by the tensor equation \(TB=BT\). This simple rule yields at most three component relations which are the generators of many known universal relations for isotropic elasticity theory, including the well- known universal rule for a simple shear. Universal relations for four families of nonhomogeneous deformations known to be controllable in every incompressible, homogeneous and isotropic elastic material are exhibited. These same universal relations may hold for special compressible materials. New universal relations for a homogeneous controllable shear, a nonhomogeneous shear, and a variable extension are derived. The general universal relation for an arbitrary isotropic tensor function of a symmetric tensor also is noted.
