A random field formulation of Hooke's law in all elasticity classes
arXiv:1602.09066 · doi:10.1007/s10659-016-9613-2
Abstract
For each of the isotropy classes of elastic materials, we consider a homogeneous random field taking values in the fixed point set of the corresponding class, that is isotropic with respect to the natural orthogonal representation of a group lying between the isotropy group of the class and its normaliser. We find the general form of the correlation tensors of orders and of such a field, and the field's spectral expansion.
