METHOD OF TESTING STRENGTH OF BRITTLE MATERIAL

摘要

FIELD: testing engineering. ^ SUBSTANCE: method comprises cyclic loading of the article with gradually increasing amplitude from zero up to the appearance of the signals of acoustic emission and recording maximum loading of the later cycles that are used for judging the strength of the article. The maximum loading of the cycle increases only up to the appearance of acoustical emission before the end of unloading . The load is used for judging the maximum nondestructive loading. ^ EFFECT: enhanced reliability.
