Description

Изобретение относитс  к испытательной технике, а именно к способам определени  механических свойств материалов .The invention relates to a testing technique, and specifically to methods for determining the mechanical properties of materials.

Известен способ определени  модул  упругости при раст жении, основанный на свойствах отраженного луча (метод Марте НС а) Ц .The known method for determining the tensile modulus, based on the properties of the reflected beam (Marté method a) C.

Однако известный способ не позвол ет точно определ ть модуль упругости материалов типа стекло- и углепластиков в услови х высоких температур.However, the known method does not accurately determine the elastic modulus of materials such as glass and carbon plastics under high temperature conditions.

Дл  повышени  точности определени  модул  упругости в услови х высоких температур, последовательно по перемещению захватов измер ют удлинени  двух образцов с различной длиной рабочей части и одинаковой- площадью поперечного сечени , а дл  вычислени  модул  упругости используют отношение разности удлинений к разности длин испытываемых образцов.To increase the accuracy of determining the elastic modulus under high temperature conditions, the elongations of two samples with different working lengths and the same cross-sectional area are measured by moving the grippers, and the ratio of the difference of elongations to the difference of the lengths of the tested samples is used to calculate the elastic modulus.

На фиг. 1 показаны испытуемые образцы; на фиг. 2 дана диаграмма в координатахнагрузка-деформаци .FIG. 1 shows the tested samples; in fig. 2 shows a diagram in coordinates load-deformation.

Испытание образцов при определении модул  упругости материалов на раст жение провод т на установках, позвол киих измер ть деформацию образцовSamples testing in determining the modulus of elasticity of materials for stretching is carried out on installations, allowing them to measure the deformation of the samples

по перемещению захватов. Испытывают два образца 1 и 2 с одинаковым поперечным сечением, но различной длиной рабочей части а и а + Е . При одних и тех же услови х и режимах последовательно измер ют абсолютное удлинение двух образцов с различной длиной рабочей части, определ ют относительное удлинение, равное разнос10 ти удлинений испытываемых образцов, отнесенное к разности длин этих образцов , и, использу  найденное относительное удлинение, вычисл ют модуль упругости материала при раст жении.by moving the grippers. Test two samples 1 and 2 with the same cross section, but with different lengths of the working part a and a + E. Under the same conditions and modes, the absolute elongation of two samples with different lengths of the working section is sequentially measured, the relative elongation equal to the difference of the elongations of the test samples, related to the difference of the lengths of these samples, is determined, and using the found relative elongation, modulus of elasticity of the material upon stretching.
