METHOD OF DETERMINATION OF THE ELASTICITY MODULUS WITH CRYSTALLINE STRUCTURE IN DIFFERENT CRYSTALLOGRAPHIC DIRECTIONS

摘要

The invention relates to methods of determination of strength properties of materials, in particular to determination of the module of elasticity of material with crystalline structure in different crystallographic directions, and can be used for determination and prediction of mechanical properties of those. A method for the determination of the module of elasticity of material with crystalline structure in different crystallographic directions consists in measurement of the period of crystalline structure and calculation of the module of elasticity for different crystallographic directions by formula relating the binding energy of atoms in given crystallographic direction, period of the lattice and the constant depending on the type of the lattice. The technical result is in decrease of labor consumption, possibility of prediction of mechanical properties of material with account of anisotropy of properties, increase of accuracy of determination of the elasticity modulus (Young modulus) in different crystallographic directions and simplification of the method of its determination.
