Young's and shear moduli and Poisson's ratio of polycrystalline solids consisting of two-dimensional quadratic and three-dimensional cubic randomly oriented grains of the same size and shape is studied. Considered polycrystals are initially unstraine

Fourth-rank symmetric tensors, that embody the elastic properties of crystalline anisotropic substances, were constructed for all 2D crystal systems. Using them we obtained explicit expressions for inverse of Young's modulus E(n), inverse of shear mo

Anisotropies of Young's modulus E, the shear modulus G, and Poisson's ratio of all 2D symmetry systems are studied. Simple necessary and sufficient conditions on their elastic compliances are derived to identify if any of these crystals are completel

Using bases of fourth rank tensorial bases of complete Voigt's symmetry elaborated by Walpole we obtained expressions for inverse of Young's modulus E, inverse of shear modulus G and Poisson's ratio, which depend on components of the stiffness tensor

We show that the problem of finding components of longitudinal normals for all piezoelectric classes is equivalent to the problem of solving two sets of two polynomial equations up to 6th degree. It is proved that the number of longitudinal normals f

The two components, coherent and non-coherent, of acoustical excitations accompanying heat pulse generation have been investigated in GaAs. It was shown that delta-doped layers imbedded into the GaAs crystal exhibit the peculiar property to be sensit
