A. Danescu et Am. Tarantino, ANISOTROPIC POLYNOMIAL CONSTITUTIVE-EQUATIONS FOR ELECTROELASTIC CRYSTALS, Zeitschrift fur angewandte Mathematik und Physik, 48(6), 1997, pp. 857-873
This paper is concerned with polynomial constitutive relations for ele
ctroelastic crystals. We generalize previous results of [1], and we em
phasize the role of disjoint union decompositions in the representatio
n problems. Our method, essentially a ''group-average method'' [2], pr
ovides the number of coefficients needed for the 32 crystallographic g
roups for polynomial relations up to degree 5.
