Description
формацию соответственно сжати и раст жени . Измер ют одггаврсмснн.о с помощью тензодатчнков Ri-R, амплитуды поперечной и продольной деформации и определ ют коэффициент jLi Пуассона по формуле:compression and expansion, respectively. Measurement of the waveform with the help of strain gauges Ri-R, the amplitude of transverse and longitudinal strain, and determine the Poisson's coefficient jLi by the formula:
поп pop
Р- - - 1R- - - 1
продprod
где ЕКОП - амплитуда поперечной деформации;where ECOP is the transverse strain amplitude;
Епрол - амплитуда продольной деформации .Eprol - the amplitude of the longitudinal strain.
Данный способ позвол ет определить .коэффициент Пуассона малопластичных материалов , снижает трудоемкость измерений, кроме того, измерени не завис т от геометрических размеров исследуемых образцов, что позвол ет повысить точность измерений и уменьшить требовани к точности изготовлени образцов. Относительна погрешность определени коэффициента Пуассона данным способом не превышает 1%.This method allows one to determine the Poisson's ratio of low-plastic materials, reduces the laboriousness of the measurements, moreover, the measurements do not depend on the geometric dimensions of the samples under study, which allows to increase the measurement accuracy and reduce the requirements for the accuracy of sample production. The relative error in determining the Poisson's ratio in this way does not exceed 1%.
