Description
Изобретение относитс к испытани м материалов иа прочность, а именно к образцам дл оценки склонности материала к хрупкому ра ушению.The invention relates to the testing of materials and their strength, namely to samples for assessing the tendency of a material to brittle dilution.
Известен образец дл оценки склонноети материала к хрупкому разрушению, снабженный надрезом в рабочей части A known sample for estimating the tendency of the material to brittle fracture, provided with a notch in the working part
Недостатком этого образца вл етс низка точность при испытани х, так как продвижение трещины происходит скачко- образно и в услови х неравномерного, не контролируемого нагружени .The disadvantage of this sample is low accuracy during testing, since the crack propagation occurs abruptly and under conditions of non-uniform, uncontrolled loading.
Известен образец дл оценки склонности материала в хрупкому разрушению, снабженный Т-образной головкой с надрезом, размешеннымпо оси симметрии головкиA known sample for assessing the tendency of a material in brittle fracture, provided with a notched T-shaped head, placed along the axis of symmetry of the head
Указанный образец вл етс наиболее близким к изобретению по технической сущности и достигаемому результату.The specified sample is the closest to the invention to the technical essence and the achieved result.
Недостатком этого образца вл етс низка точность оценки, так как при его натружении по вл етс неравномерна нагрузка в зоне продвижени трещин.The disadvantage of this sample is the low accuracy of the estimate, since when it is thinned, an uneven load appears in the zone of crack propagation.
Цл поБЫшевш точности оценки образец выполнен кольцевым и снабжен второй Т-образной головкой, ось симметрии которой совпадает с осью симметрии первой.The accuracy of the evaluation of the sample is made annular and provided with a second T-shaped head, the axis of symmetry of which coincides with the axis of symmetry of the first.
На фиг. 1 изображен предлагаемый образец, вид спереди на фиг. 2 - тоже, вид сверху.FIG. 1 shows the proposed model, front view in FIG. 2 is also a top view.
Он содержит кольцевую часть 1, Т-образной головки 2 и 3, надрез 4, отверсти 5 и 6 в головке, 3.It contains an annular part 1, a T-shaped head 2 and 3, a notch 4, holes 5 and 6 in the head, 3.
Образец испытывают следующим образом .В кольцевую часть 1 образца вставл ют кольцевые полусектора 7, 8, а межпу образцами и -секторами размещают упругие элементы 9.The sample is tested as follows. The annular half-sectors 7, 8 are inserted into the ring part 1 of the sample, and elastic elements 9 are placed between the samples and the-sectors.
Затем нагружают раст гивающими усили ми кольцевую часть 1 образца до требуемого напр жени и дополнительно нагружают через отверсти 5, 6 надрез 4 головки 3.Then, the ring portion 1 of the specimen is loaded with tensile forces up to the required voltage, and the notch 4 of the head 3 is additionally loaded through the holes 5, 6.
