Abstract
The Cosserat theory is used for the description of granular materials, where — in consequence of the microstructure of the material — additional rotational degrees of freedom come into play. This leads to unsymmetric stress and strain tensors as well as to a couple stress tensor, thus requiring extended constitutive relations with additional material parameters. The goal of the present contribution is the identification of these additional parameters on the basis of the solution of an inverse problem of a non-homogeneous boundary-value problem such as the biaxial test.
