通过建立一套能够实现在力场、电场、温场等多场耦合条件下测试的小样品力学性能测试系统,使得小样品在近真实的多场耦合条件下得到评价:在小样品力学性能测试系统的基础上,通过设计模具和引入电场,实现了力电耦合下的小样品的动态力学性能的测试;通过设计模具和高温炉引入温场,可以对热障涂层、陶瓷等材料进行高温条件下的力学性能测试。通过引入声发射仪和模具设计,在测试材料力学性能的同时,可以实时监控材料内部结构发生的变化。多场耦合MSP测试系统的建立,为新型无机材料在多场耦合下的力学性能研究提供了系统的测试平台,为材料使用的可靠性和稳定性研究奠定了基础。
By setting up a set of small-sample mechanics performance test system that can test under many coupling conditions such as force field, electric field and temperature field, the small sample can be evaluated under near real multi-field coupling conditions. In the small sample mechanical property test On the basis of the system, the dynamic mechanical properties of the small sample under the force-electric coupling are tested by designing the mold and introducing the electric field. By designing the mold and the introduction of the temperature field in the high temperature furnace, the thermal barrier coatings, ceramics and other materials can be subjected to high temperature Mechanical properties of the test conditions. By introducing acoustic emitters and mold designs, the mechanical properties of materials can be tested while the changes in the internal structure of the material can be monitored in real time. The establishment of multi-field coupled MSP test system provides a systematic test platform for the study of mechanical properties of new inorganic materials under multi-field coupling, which lays the foundation for the research on the reliability and stability of materials.
