METHOD FOR DETERMINING MECHANICAL CHARACTERISTICS OF MATERIALS Russian patent published in 2012 - IPC G01N3/42 

FIELD: machine building.

SUBSTANCE: introduction of spherical indenter to tested material is performed at continuously increasing load, recording of indentation diagram with loading and unloading branches is performed and measurement of residual depth of indent after full unloading is carried out. Indentation diagram recording is performed in "load - elastoplastic approximation of indenter and material" coordinates, load, elastic approximation of material and indenter and residual depth of indent is measured, which correspond to the beginning of decrease of derivative of load function from elastoplastic approximation, and elastic material deformation is subtracted from common elastic approximation.

EFFECT: reducing labour intensity, improving accuracy, efficiency and enlarging functional capabilities of the method.
