Finite deformations of polar elastic media
The curvilinear coordinates in orientation space are considered. The Euler angles are an example of such coordinates. The inertia conservation law is replaced here by a constitutive relation. From the physical point of view, this relation is more general and seems to be better justified than the mentioned law. Within the framework of the polar continuum theory, a micromorphic structure is discussed. Some remarks on the principle of a material frame-indifference are also presented.
