Description
По известному способу определени прочностных свойств материалов нагружают испытуемый образец и без сн ти прилагаемой нагрузки измер ют усилие и физическую характеристику материала, но величине которых суд т о напр жении в испытуемом образце. Известным способом невозможно определить начальную стадию разрушени образца, образование н развитие микротрещин в хрунких материалах , например в литом бериллии.According to a known method for determining the strength properties of materials, the sample under test is loaded, and without removing the applied load, the force and physical characteristics of the material are measured, but the magnitude of which is judged on the voltage in the sample under test. In a known way, it is impossible to determine the initial stage of sample destruction, the formation and development of microcracks in crystalline materials, for example, in cast beryllium.
Предлагаемый способ отличаетс тем, что испытуемый образец включают в электрическую цепь и за физическую характеристику принимают электрическое сопротивление цепи. Это повышает точность определени момента возникновени микротрещин.The proposed method is characterized in that the test sample is included in an electrical circuit and the electrical resistance of the circuit is taken as a physical characteristic. This improves the accuracy of determining the time of occurrence of microcracks.
