Abstract

Изобретение относитс  к испытани м , в частности к образцам дл  усталостных испытаний,, Цель изобретени  - обеспечение повышени  достоверности определени  усталостных характеристик за счет сохранени  посто нной средней по сечению образца амплитуды напр жений Образец, содержащий два захватных участка 1 и 2 с криволинейными границами и расположенный между ними рабочий участок 3, циклически нагружаюто За счет поременности длины рабочего участка на нем обеспечиваетс  градиент напр жений, а за счет посто нства его тол ичны обеспечиваетс  посто нное среднее г грлжение по сечению рабочего учо г-Тго 2 ил.   «The invention relates to tests, in particular to samples for fatigue tests,. The purpose of the invention is to provide an increase in the reliability of the determination of fatigue characteristics by maintaining a constant voltage average across the sample, the sample amplitude containing two gripping sections 1 and 2 with curvilinear boundaries and located between them is a working section 3, cyclically loaded. Due to the temporary length of the working section, a voltage gradient is provided on it, and due to the constant thickness of the working section There is a constant average ggr over the section of the working district of g-Tgo 2, il.
