智能材料力电磁耦合行为的鼓泡表征方法及实验系统研制

新型电磁智能材料不仅具有传统电磁材料的特点，而且还有特殊的磁电耦合响应特性，具有重要的应用前景和国防意义。但目前人们对这类材料的研究还处于探索阶段，对其本构关系、正/逆磁电响应机理、界面耦合机理和调控机制等关键科学问题尚未深入理解和解决，进而限制其广泛应用。由于它们具有非均质、力电磁全耦合物理力学行为等特性，导致现有实验测试表征技术及仪器遇到了全新的挑战，亟待发展新的试验测试表征方法及仪器。本项目通过对现有的鼓泡法及测试平台进行改造和功能升级，设计和组装电场加载系统、磁场加载及标定系统、电学量和磁学量测试系统以及高精度三维应变光学测试系统，提出一套力电磁耦合加载和力电磁耦合实时测试的实验新表征技术及测试系统，为掌握电磁智能材料多场耦合行为和验证力电磁耦合场理论研究结果提供一个强有力的实验平台和研究手段，为新型智能材料、结构及其器件的多场耦合响应、破坏机理和产品质量的研究起到重要推动作用。

Novel electromagnetic intelligent materials have not only the characteristics of traditional electromagnetic materials, but also special magnetoelectric coupling response functions, which have important application prospects and defense significance. But the investigations of this kind of materials are still in the primary stage. Many key scientific problems such as constitutive relation, normal/reverse magnetoelectric response mechanisms, interfacial coupling mechanisms and control mechanisms have not been deeply understand and study at present, which limit their widespread applications. Especially they have heterogeneous, complicated force-electromagnetic coupled physical and mechanical behaviors and multilayer interface coupling characteristics at micro scales, which lead to new challenges and difficulties of current experimental characterization techniques and instruments. Other new test characterization methods and apparatus are desired to be developed. This project is based on the transformation and upgrade functions of existing blister method and test platform, and assemble electric loading system, magnetic field and calibration system, electrical testing system, magnetic measurement system and high precision 3D strain optical test system. We put forward a set of new characterization technique and test system with forece-electromagnetic coupling loading and forece-electromagnetic coupling real time test functions, which will provide a strong experimental platform and research methods to study multi-field coupling behaviors of electromagnetic intelligent materials and verify theoretical results of force-electric-magnetic coupling field theory. The system would play an important role in promoting the developments of multi field coupled response, failure mechanisms and products quality of other new intelligent materials, structure and their devices.
