DEVICE FOR BEND-TESTING OF SPECIMENS Russian patent published in 1994 - IPC

FIELD: test technology, bend-testing. SUBSTANCE: device has supports 2, 4, 5 for specimen 3, levers 6, 7, torque link 8, 9 with retainers 12, 13, pusher 11 with eccentric 10. On rotating eccentric 10 retainers 12 and 13 are switched on and levers 6, 7 with rollers 4, 5 are rotated through links 8, 9 and a specimen to be tested is bent either on two cantilevers or on one of the cantilevers when one of the retainers is activated. The device is used for testing specimens of different materials. EFFECT: widened operating capabilities due to testing both at simultaneous and alternative loading of cantilevers with synchronous or asynchronous change of the length of bend cantilevers. 1 dwg
