Establishment and Application of the MSP Test under Multi-Field Coupling

The mechanical properties testing equipment for small specimens, to achieve the mechanical properties testing under the mechanical, electrical and mechanical-electrical coupling field was set up. On the basis of dynamic materials testing machine, by design and configuration AC-DC power supply, acoustic emission equipment, etc, we developed mechanical properties testing equipment for small specimens, to achieve the mechanical properties testing under the mechanical, electrical and mechanical-electrical coupling field, and real-time monitoring for material damage and failure process. Through the design of the mold and the acquisition of the AC-DC power supply, the system can test the mechanical properties of piezoelectric ceramics under electromechanical coupling field. Through the design of the mold and the acquisition of high-temperature furnace temperature field, the system can test the mechanical properties of thermal barrier coatings and refractory ceramics. Through the design of the mold and the acquisition of acoustic emission, the system can monitor the changes in internal structures of material during the test of the mechanical properties. The establishment of the system provides a full appraisal system of testing the mechanical properties of piezoelectric ceramics and Structural Ceramics under Multi-field coupling field. The establishment of the system is useful for the reliability and stability of the material.
