Анализ напряженно-деформированного состояния в шейке плоского образца высокопрочной стали при разрушении

The technique for plastic strain measuring in metals by means of TV-optical measuring complex TOMSC is discussed. Using high-strength martensitic aircraft steel as an example we calculate linear and shear strain component distributions, strain-rate intensity and stress in the symmetrical neck of a flat specimen. The results obtained are compared with appropriate distributions for the inclined neck.
