The invention discloses a micro
mechanical property test clamping device for a material under a combined loading mode. The clamping device comprises a pedestal capable of being fixed on the top surface of a working table, a lower connection main shaft connected with the top of the pedestal, a lower fan-shaped
flange disk connected with the top of the lower connection main shaft, an upper fan-shaped
flange disk which is located above the lower fan-shaped
flange disk and is separated from the lower fan-shaped flange disk and an upper connection main shaft connected with the upper fan-shaped flange disk, and further comprises a clamping structure for clamping a test piece. Compared with the prior art, the micro
mechanical property test clamping device for the material under the combined loading mode has the advantages that by conversion of a through hole
bolting position between the upper connection main shaft and the upper fan-shaped flange disk as well as a through hole
bolting position between the lower connection main shaft and the lower fan-shaped flange disk, and cooperation with the test piece clamping structure with different clamping
modes, a tester can conveniently complete a fracture property test of different types of materials, such as tensile failure, shear fracture, tear fracture,
tensile shear combined fracture and tensile tear fracture.
