An irreducible, non-polynomial representation for an anisotropic constitutive equation being an explicit relation between two symmetric, second-order tensors is established in this article.Abstract:
An irreducible, non-polynomial representation is established for an anisotropic constitutive equation being an explicit relation between two symmetric, second-order tensors. The considered material anisotropy is characteristic of two non-orthogonal and mechanically non-equivalent privileged directions in plane. Particular cases of orthotropy and of cubic symmetry are analyzed in detail. An illustrative example referring to infinitesimal elasticity is presented in order to compare the developed representation with the classical Hooke law.
Es wird eine nichtreduzierbare Darstellung, die keine Polynomdarstellung ist, fur ein anisotropes Stoffgesetz, welches eine explizite Beziehung zweier symmetrischer Tensoren zweiter Stufe herstellt, formuliert. Die Anisotropie des Materials ist charakterisiert durch zwei nichtorthogonale, mechanisch ungleich bevorzugte Richtungen in der Ebene. Einzelne Falle von Orthotropie und kubisher Symmetrie sind im einzelnen untersucht. Um die entwickelte Darstellung mit dem klassischen Hookeschen Gesetz zu vergleichen, ist ein erlauterndes Beispiel zur infinitesimalen Elastizitat angefugt.read more

TL;DR: In this paper, a unified theory of the relations observed between load and deformation for elastic solids of various shapes, sizes, and compostions is presented, where the elastic character of the materials to which the theory is applicable may be loosely described as follows: if a body of elastic material is subjected to a load, it will be deformed and on the removal of the load will regain its initial dimensions and shape.

TL;DR: In this article, it was shown that the symmetric isotropic matrix polynomial in any number of symmetric 3 × 3 matrices can be expressed as a symmetric ISP polynomials, in which each of the matrix products is formed from at most six matrices and has one of a certain number of forms which are explicitly given.
