Abstract

Использование при определении модул  упругости высокоэластичных листовых материалов . Сущность изобретени : центральную часть образца 1 в виде мембраны толщиной h и радиусом п закрепл ют между двум  дисками 2 и 3 радиусом Г2, Затем раст гивают образец радиальными усили ми и закрепл ют его по контуру. Далее прикладывают к центру дисков 2 и 3 осевое нормальное усилие. Фиксируют прогиб в центре мембраны. По достижении заданного прогиба фиксируют осевое усилие Р. Модуль упругости рассчитывают по приведенной формуле. 1 табл., 2 ил.Use when determining the modulus of elasticity of highly elastic sheet materials. SUMMARY OF THE INVENTION: The central part of sample 1 in the form of a membrane with thickness h and radius n is fixed between two disks 2 and 3 with radius T2. Then, the sample is stretched with radial forces and fixed along the contour. Next, apply to the center of the disks 2 and 3 axial normal force. Fix the deflection in the center of the membrane. Upon reaching a given deflection, fix the axial force R. The modulus of elasticity is calculated using the above formula. 1 tab., 2 Il.
