Multi field coupling dynamics analysis has always been a problem of great concern. As the basic elements of machinery, the properties of materials such as mechanics, thermodynamics, and electromagnetism play an essential role in mechanical design. On the one hand, in recent years, the material property system in a single discipline has tended to be perfect, but machinery usually works under the action of multi-field coupling, and there are often multiple design indicators that are difficult to reconcile in terms of weight and scope of action. Therefore, it is quite difficult to use the single-field performance index of the material to achieve the design goal of multi-field coupled machinery at one time. On the other hand, due to the development of science and technology, the natural balance has been greatly changed. It is foreseeable that the important direction of the next industrial revolution should be to develop in harmony with nature on the basis of meeting the needs of human survival and production. While developing new materials, we must also pay attention to the comprehensive utilization rate of materials, and cannot blindly pursue the ultimate performance in a certain aspect. Therefore, with the help of the proposed axiomatic principle of dynamic behavior of materials, a new description method of multi-field coupling index is proposed. In the future, one of these indicators can be used to develop multi-field coupled mechanical design methods for mechanical design, and the second is to use these indicators to develop evaluation criteria that can describe the environmental conditions of materials, which has certain practical significance.
