FIELD: tests of strength properties of materials; methods of determination of yield point. ^ SUBSTANCE: proposed consists in use of filament-like monocrystals and measurement of crystal lattice spacing by roentgen-structural method followed by calculation of yield point by the following formula: =c/(x/a0)2, where c is coefficient determined at point x=0.07a0 and max=G*x/a0, where a0 is crystal lattice spacing; x is displacement at shear. ^ EFFECT: reduced labor consumption; possibility of prediction of mechanical properties of material with its anisotropy taken into account. ^ 1 tbl |
