Изобретение относитс  к области испытани  материалов на прочность, а именно к образцам дл  испытани  на раст жение.This invention relates to the field of strength testing, namely, tensile specimens.

Известен образец дл  испытани  на раст жение , содержащий две захватные и рабочую части 1.A known tensile test specimen containing two gripping and working parts 1.

Известен также образен дл  испытани  на раст жение, содержапиш две захватные части и рабочую часть с продольными прорез ми 2.It is also known to be formed for tensile testing, containing two gripping parts and a working part with longitudinal slits 2.

Этот образец  вл етс  наиболее близким к изобретению по технической сущности и достигаемому результату.This sample is the closest to the invention according to the technical essence and the achieved result.

Недостатком известных образцов  вл етс  низка  точность при испытании тонколистовых материалов.A disadvantage of the known samples is the low accuracy when testing thin-sheet materials.

Целью изобретени   вл етс  повьинение точности испытани  тонколистового материала .The aim of the invention is to improve the accuracy of the test sheet material.

Дл  достижени  этой пели прорезей в рабочей части выполнено нечетное количество , ширина каждой прорези составл ет не менее п ти толщин образца, длина - не менее двадцати толщин, а щирина перемычек между прорез ми составл ет не более п ти толщин образца.To achieve this, the slots in the working section are odd in number, the width of each slot is at least five thicknesses of the sample, the length is at least twenty thicknesses, and the width of the bridges between the slits is no more than five thicknesses of the sample.

На чертеже приведен образец, общий вид.The drawing shows a sample, a general view.

Образец содержит захватные части I и 2, рабочую часть 3 с продольными прорез ми 4, 5 и 6 и иерсмычками 7, 8, 9 и 10. Ширина Н ирорезеГ 4, 5 и 6 составл ет не менее п ти толщин образца и одинакова дл  всех нрорезей. д.шна -t прорезей пс менее двадцати толщин, а цщрпна h перемычек 7, 8. 9 и 10-не более п ти толщин образца и одинакова дл  все.ч iepeMi iчек .The sample contains the gripping parts I and 2, the working part 3 with the longitudinal slits 4, 5 and 6 and the yerms 7, 8, 9 and 10. The width H of the rip 4, 5 and 6 is at least five thicknesses of the sample and the same for all nrorezy. The d-sh of ps is less than twenty thicknesses, and the h of jumpers 7, 8. 9 and 10 are no more than five times the thickness of the specimen and the same for all iepeMi ichek.

Образец испытывают следующим образом .The sample is tested as follows.

Захватные части 1 и 2 помещают в ты испытательной мащины и нагружают образец раст гивающим усилием до разрушени  образца. Так как одинаковы размеры перемычек 7, 8, 9 и 10 и одинаковы размеры прорезей 4, 5 и 6, то усили  между перемычками распредел ютс  пропорционально жесткости каждой перемычки, завис щей в данном случае только от модул  унругости материала . Измер   деформацию каждой перемычки , можно определить распределениеThe gripping parts 1 and 2 are placed in the test bed and the sample is loaded with a tensile force until the sample is destroyed. Since the same dimensions of the jumpers 7, 8, 9 and 10 and the same dimensions of the slots 4, 5 and 6, the forces between the jumpers are distributed in proportion to the stiffness of each jumper, depending in this case only on the modulus of the material elasticity. By measuring the deformation of each jumper, you can determine the distribution

прочностных характеристик материала в образце.strength characteristics of the material in the sample.
