METHOD OF DETERMINATION OF TOUGHNESS FACTOR OF WELD METAL BREAKING Russian patent published in 1994 - IPC

Abstract RU 2019809 C1

FIELD: test equipment. SUBSTANCE: method consists in production of specimen, bringing-on of stress concentrator and crack and subsequent test up to breaking, stress concentrator and crack are made by edge welding of two preliminarily grooved, polished plates contacting on chamfered polished surfaces, compressed by distributed load selected from condition δ<0,25δ_y, where δ - compression stresses on plate chamfered surfaces, d_y - yield point. EFFECT: enhanced accuracy of estimation of base metal breaking toughness. 1 dwg
