MATERIAL STRENGTH TEST TECHNIQUE INCLUDING MEASUREMENT OF SPECIMEN ELECTRICAL RESISTANCE Russian patent published in 1997 - IPC

Abstract RU 2087905 C1

FIELD: measurement technology; nondestructive tests of solid materials. SUBSTANCE: to determine strength of specimen in the form of carbon filament built up of equal-length elementary carbon filaments, electrical resistance of carbon filament and breaking load of elementary fiber are measured. Breaking load of carbon filament is found from equation P=P_i•R_i/R, where P_i is breaking load of elementary fiber; R is carbon filament resistance; R_i is elementary fiber resistance. EFFECT: facilitated procedure. 2 dwg
