METHOD OF DETERMINING DYNAMIC MICRO-RIGIDITY OF WEDGE-SHAPED ARTICLE Russian patent published in 2006 - IPC G01N3/48

Abstract RU 2290621 C1

FIELD: testing engineering.

SUBSTANCE: method comprises penetrating indenter into the surface layer of the wedge-shaped article. The rigidity of the indenter is much higher that that of the article. The indenter is penetrated from the side of the wedge edge, perpendicular to it, and over one of the surfaces of the blade. The dynamic micro-rigidity is determined by dividing the kinetic energy of impact by the volume of displaced material.

EFFECT: enhanced reliability.
