Abstract

The invention relates to a test-piece clamp for multi-load coupling loading and a multi-physics field coupling loading method thereof, and belongs to the field of material micro-mechanical property testing. By machining a groove in the clamp, putting a test piece into the groove and compacting through pressing plates, application of stretching, bending, torsion, and other mechanical loads onto the test piece by the clamp is achieved. Conductive heating is performed by bringing a silicon nitride heating sheet and the test piece into contact, and temperature feedback is achieved by a thermocouple, thus achieving application of thermal-field loading onto the test piece to be tested. Electric-field loading to the test piece is achieved by providing the test piece with a controllable electric current. Magnetic-field loading to the test piece to be tested is achieved through two magnetic induction coils. The structure is simple and compact, the method is scientific and reasonable, and properties are stable and reliable. Large-range temperature loading, accurate electric current loading and controllable magnetic field loading for a test piece material to be tested can be achieved. Composite-load loading and stimulation of a thermal field, an electric field and a magnetic field, which are closer to service conditions, for material testing can be provided. The test-piece clamp and the method have important theoretical significance and application value.

Description

technical field [0001] The invention relates to the technical field of material microscopic properties, in particular to testing of material micromechanical properties, in particular to a multi-load coupled loading specimen fixture and a multi-physics field coupled loading method in the testing of material micromechanical properties. It belongs to precision instrument components and precision drive transmission unit components. Background technique [0002] In recent years, the research work on the testing of material micromechanical properties under multiple loads and multi-physics field coupling conditions has attracted more and more attention from the international academic and engineering communities. In the field of engineering, the accidental damage and failure of materials and their products often lead to economic losses and even serious accidents. The reason why materials and their products have usually been tested for mechanical properties but unexpected failures m...
