The paper presents the equations of the linear moment theory of elasticity for the case of arbitrary anisotropy of material tensors of the fourth rank. Symmetric and skew-symmetric components are distinguished in the defining relations. Some simplified variants of linear defining relations are considered. The possibility of Cauchy elasticity is allowed when material tensors of the fourth rank do not have the main symmetry. For material tensors that determine force and moment stresses, eigenmodulus and eigenstates are introduced, which are invariant characteristics of an elastic moment medium. For the case of plane deformation and constrained rotation, an example of a complete solution of a two-dimensional problem is given when there are only shear stresses. For anisotropic and isotropic elastic media, the solutions turn out to be significantly different.
Keywords: moment theory of elasticity, asymmetric stress tensors, defining equations, elastic modulus, fourth-rank tensors, pure shear, constrained rotation, two-dimensional problem. .
