APPARATUS FOR MATERIALS SAMPLES TEST BY FATIGUE Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: apparatus has disks 2, 3, 10 with rotation drives 6, 7; flexible facing 5; platform 8 with drive 9. As disks 2, 3 are rotating sample 4 is loaded by a reducing force during pressing it to the facing and section site of reduction is so much the bigger, the bigger is motion of platform 8 in direction to the facing. EFFECT: apparatus is used for tests of ring-shaped materials and pieces with application of loading both along generatrix and section site on outer surface of sample with symmetric orthographic epure projection of reducing facing. 1 dwg
