| 英文摘要 | Soft magnetorheological elastomer (s-MRE) is fabricated by dispersing magnetic particles within the elastomer matrix. Its mechanical properties dramatically change under the applied magnetic field, exhibiting a typical magnetorheological (MR) effect. This property provides s-MRE with the potential for application in vibration control. During vibration control application scenarios, s-MRE-based vibration control devices are often subjected to asymmetric cyclic loads, for instance, the structure's self-weight and dynamic loads (e.g., wind or traffic loads), which result in a decay of the stress response with cyclic loading (mainly short cycle loading), referred to as the cyclic stress softening. If the influence of cyclic stress softening is ignored, the evaluation of s-MRE-based vibration control devices may exhibit unwarranted optimism and lack sufficient reliability, which may cause safety hazards. However, a literature review reveals limited investigation on the cyclic stress softening of s-MRE. To address this research gap and enhance the performance evaluation of s-MRE-based devices, this work experimentally characterizes the influence of mechanical loads and magnetic fields on the cyclic stress softening of isotropic s-MRE. The test results indicate that peak strain plays a dominant role in the occurrence of cyclic stress softening and an increased strain rate further amplifies this effect. Furthermore, the presence of a magnetic field positively influences the mechanical behaviour of isotropic s-MRE and concurrently intensifies the cyclic stress softening effect. This research enhances the understanding of the cyclic stress softening in s-MRE, thereby benefiting the long-term advancement of s-MRE-based development and design. |
