Description
(54) СПОСОБ ОПРЕДЕЛЕНИЯ СОПРОТИВЛЯЕМОСТИ МАТЕРИАЛА ДЕФОРМИРОВАНИЮ(54) METHOD FOR DETERMINING THE RESISTANCE OF MATERIAL DEFORMATION
делении статического модул упругости стандартным способом. При этом регистрируютс амплитудные значени напр жени и деформации в течение 5-6 циклов. Плавность переменного нагружени позвол ет более точно определить величину статического модул упругости.dividing the static modulus of elasticity in a standard way. At the same time, amplitude values of stress and strain are recorded for 5-6 cycles. The smoothness of the variable loading makes it possible to more accurately determine the magnitude of the static elastic modulus.
После нагружени образца в течение 5- 6 циклов при низкой частоте (примерно до 0,01 Гц) увеличивают частоту нагружени по заданной программе усталостных испытаний , и в течение первых 100 циклов определ ют амплитудные значени напр жений и деформации, по которым рассчитывают значени динамического модул упругости.After loading the sample for 5-6 cycles at a low frequency (up to about 0.01 Hz), the loading frequency is increased according to a predetermined fatigue test program, and during the first 100 cycles, the amplitude values of the stresses and strains are calculated, from which the dynamic modulus values elasticity.
По данным статического и динамического модулей упругости рассчитываетс их отношение-характеристика сопротивл емости материалов деформированию.According to the data of the static and dynamic moduli of elasticity, their ratio-characteristic of the resistance of materials to deformation is calculated.
Определение указанных модулей упругости на одной испытательной машине без перестановки образца повышает точность их определени и сокращает врем проведени эксперимента.The determination of these elastic moduli on a single testing machine without rearranging the sample improves the accuracy of their determination and shortens the time of the experiment.
