CENTRIFUGAL TEST BENCH FOR TENSILE TESTING OF SAMPLES OF BRITTLE ROCKS AND OTHER BRITTLE MATERIALS IN PLANE STRESS STATE

摘要

A centrifugal test bench for tensile testing of samples of brittle rocks and other brittle materials at flat stressed state comprises a vertical shaft, rotary platform with cassette, vacuum chamber, rotary drive of the platform, amplitude restrictor and damper of vibrations of rotary platform, bearing lubrication system, vacuum system and system for control of rotary samples speedup. The cassette design provides sample loading with centrifugal forces of their own masses in horizontal plane.
