摘要
致流变体是智能材料的一个重要分支 ,其构成有磁流变体 (MR)和电流变体 (ER)。这种材料可以在外加场强 (电场或磁场 )作用下 ,在毫秒级时间内从牛顿流体变为剪切屈服应力较高的粘塑性体 ,且这种转变可控、连续、可逆 ,因此 ,它有着很广阔的应用前景。主要介绍了这种材料的组成、特性和本构关系 。
The controllable fluid is one of embranchments of intelligent material, which includes electrorheological (ER) materials and magnetorheological (MR) materials.It can be transformed from the Newton fluid into the viscoplastic solid with finite yield shear stress within millisecond when an electric field or a magnetic field is applied, and the transformation is controllable ,continual and reversible. Therefore, it can be used in many fields. In this article, the application and the future development of this material in martial field are mainly viewed and mentioned.
