Abstract
Изобретение относитс к определению механических свойств материалов на трубчатых образцах. Целью изобретени вл етс снижение материалоемкости образцов за счет уменьшени их длины. В трубчатом образце 1 со стороны его торцовых граней выполн ют по две пары 2,3 и 4,5 диаметрально расположенных продольных прорезей, причем кажда пара прорезей одного торца смещена на 90° относительно соответствующей пары прорезей другого торца. Между донь ми прорезей одного торца и донь ми ближайших к ним прорезей другого торца выполн ют канавки 6. Образец нагружают путем приложени сжимающих усилий к торцовым гран м образца, расположенным между прорез ми каждой пары. При этом в сечени х образца, ограниченных прорез ми и канавками, создаютс раст гивающие напр жени . По максимальной величине сжимающего усили и суммарной площади нетто- сечений образца с канавками определ ют предел прочности материала. 3 ил.This invention relates to the determination of the mechanical properties of materials on tubular specimens. The aim of the invention is to reduce the material consumption of the samples by reducing their length. In the tubular sample 1, two pairs of 2.3 and 4.5 diametrically arranged longitudinal slits are made on the side of its end faces, with each pair of slits of one end displaced by 90 ° relative to the corresponding pair of slits of the other end. Between the bottoms of the slots of one end and the bottoms of the adjacent slots of the other end, grooves 6 are made. The specimen is loaded by applying compressive forces to the end faces of the specimen located between the slots of each pair. In this case, tensile stresses are created in the cross sections of the specimen bounded by slots and grooves. The maximum strength of the material is determined by the maximum compressive force and the total net area of the sample with grooves. 3 il.
