Description
Изобретение относитсл к испытани м материалов и может быть испсльзовано при оценке свойств материалов и определении характеристик сопротивлени материала пластическим деформаци м.The invention relates to the testing of materials and can be used in assessing the properties of materials and determining the characteristics of material resistance to plastic deformations.
Известен способ определени характеристик сопротивлени материала пластическим деформаци м, заключающийс в том, что на образце испытуемого материала круглого сечени закрепл ют деформометр, ступенчато нагружают образец раст жением и сжатием разгружают образец до нулевого усили при каждой разгрузке и стро т диаграммы Напр жение-деформаци при раст жении и сжатии, по которым определ ют пределы упругости и текучести материала. В способе используют много образцов, нагружаемых раст жением и сжатием fl.A known method for determining the resistance characteristics of a material to plastic deformations is that a deformometer is attached to a sample of a test material of circular cross section, the sample is loaded in steps and a compression load unload the sample to zero force at each discharge, and stress-strain diagrams are drawn compression and compression, which determine the elasticity and yield strength of the material. The method uses many samples that are loaded by stretching and compressing fl.
Недостатками этого способа вл ютс низка точность, обусловленна большими norpediHOCTHMH при замере очень малых величин деформаций и эксцентриситетом приложени нагрузок , и больша трудоемкость, обусловленна необходимостью проводить испытани многих образцов.The disadvantages of this method are low accuracy, due to high norpediHOCTHMH when measuring very small deformations and eccentricity of application of loads, and greater labor intensity, due to the need to conduct testing of many samples.
Цель изобретени - повыи-ение точности и снижение трудоемкости определени характеристик сопротивлени материала.The purpose of the invention is to improve the accuracy and reduce the complexity of determining the characteristics of the resistance of the material.
Дл достижени указанной цели согласно способу определени характеристик сопротивлени материала пластическим деформаци м, заключающемус в том, что на образце испытуе10 мого материала закрепл ют деформометр , нагружают образец и стро т диагрс1М1 ы Напр жение-, деформаци при раст жении и сжатии, используют два образца треугольного симметрич15 ного сечени , нагружают каждый из образцов в плоскости симметрии сечени изгибающими моментами противоположных знаков, дополнительно регис .трируют диаграмму упруго-пласти20 ческого изгиба каждого образца, а о характеристиках сопротивлени пластическим деформаци м суд т по следующей зависимостиTo achieve this goal, according to the method of determining the characteristics of material resistance to plastic deformations, which consists in fixing a deformometer on a sample of the test material, loading the sample and constructing a stress-strain under strain and compression, two samples of triangular symmetric section, each of the samples is loaded in the plane of symmetry of the section by bending moments of opposite signs, and a diagram of elastic-plastic bending is additionally registered zhdogo sample, and the characteristics of resistance to plastic deformations is judged by the following relationship
