Abstract
Изобретение относитс к испытательной технике и может быть использовано дл определени анизотропии механических свойств материалов и направлений ее главных осей в исследуемой плоскости. Цель изобретени - снижение трудоемкости испытаний . Из заготовки материала вырезают образец в форме кругового цилиндра, ось которого перпендикул рна исследуемой плоскости анизотропии. Нагружают образец осевым сжатием и измер ют поперечные деформации образца. О главных направлени х и степени анизотропии суд т по максимальным значени м отклонений формы поперечного сечени образца от формы круга.The invention relates to a testing technique and can be used to determine the anisotropy of the mechanical properties of materials and the directions of its main axes in the plane under investigation. The purpose of the invention is to reduce the complexity of the tests. A sample in the form of a circular cylinder, the axis of which is perpendicular to the anisotropy plane under investigation, is cut out of the material blank. The specimen is loaded with axial compression and transverse strain of the specimen is measured. The main directions and degree of anisotropy are judged by the maximum deviations of the cross sectional shape of the sample from the circle.

Цель изобретени - снижение трудоемкости испытаний.The purpose of the invention is to reduce the complexity of the tests.
Способ осуществл ют следующим образом .The method is carried out as follows.
Из заготовки материала вырезают образец в форме кругового цилиндра, ось которого перпендикул рна исследуемой плоскости анизотропии.A sample in the form of a circular cylinder, the axis of which is perpendicular to the anisotropy plane under investigation, is cut out of the material blank.
Нагружают образец осевым сжатием и измер ют поперечные деформации образца .The specimen is loaded with axial compression and transverse strain of the specimen is measured.
Определ ют максимальные значени отклонений формы поперечного сечени образца от круга и по ним суд т о главных направлени х и степени анизотропии исследуемого материала.The maximum values of the deviations of the sample cross-sectional shape from the circle are determined and the main directions and degree of anisotropy of the studied material are judged from them.
П р и м е р. Из листа сплава Д16Т толщиной 30 мм вырезали перпендикул рно плоскости листа цилиндрический образец диаметром 18 мм и длиной 30 мм. Образец нагружали осевым сжатием при напр жени х 300-400 МПа. Максимальные поперечные деформации составили: Јх (1-28) 10 и Ју(2,1-6) 102 ч, степень анизотропии составила 1,97-4,7.PRI me R. A cylindrical specimen with a diameter of 18 mm and a length of 30 mm was cut out of the D16T alloy sheet with a thickness of 30 mm perpendicular to the plane of the sheet. The sample was loaded with axial compression at voltages of 300-400 MPa. The maximum transverse strains were: Јх (1-28) 10 and Ју (2.1-6) 102 h, the degree of anisotropy was 1.97-4.7.
