Abstract

Изобретение относитс  к прочностным испытани м, а именно к испытанию кольцевых разрезных образцов на ползучесть. Целью изобретени   вл етс  повышение точности испытани . Два кольцевых образца 4 вставл ют в полость захватов 1 и фиксируют их положение штифтами, при этом расположение образцов в захватах  вл етс  центрально симметричным, а центры образцов совпадают с осью хвостовиков 3 захватов. Образцы 4 нагружают посто нным усилием и регистрируют деформацию ползучести. Способ обеспечивает получение усредненных по двум кольцевым образцам характеристик ползучести при использовании испытательных машин, средств нагрева и измерени  деформаций, обычно примен емых дл  испытани  стержневых образцов. 1 ил.The invention relates to strength tests, namely to testing ring cut samples for creep. The aim of the invention is to improve the accuracy of the test. The two annular samples 4 are inserted into the cavity of the grips 1 and their position is fixed with pins, while the location of the samples in the grips is centrally symmetric, and the centers of the samples coincide with the axis of the shanks 3 of the grips. Samples 4 are loaded with a constant force and the creep deformation is recorded. The method provides creep characteristics averaged over two ring samples using test machines, means of heating and measuring the deformations commonly used for testing core samples. 1 il.
