Modification technologies and constitutive models of viscoelastic damping materials: Progress and future trends

Abstract

Viscoelastic dampers (VEDs) have attracted significant attention during the last decades, due to their enormous potential in vibration control for building structures. However, owing to the performance of VEDs being significantly affected by temperature and frequency, their wide applicability is hindered. Broadening the damping temperature range of the matrix viscoelastic damping materials (VDMs) is the key to promoting their application. The progress of polymer and nanomaterials provides a new perspective to enhance the damping performance of VDMs. Moreover, various influencing factors should also be considered in calculation models. Thus, state-of-the-art research in the modification technologies of VDMs is critically reviewed in this article. In addition, the linear and nonlinear constitutive models of VDMs are comprehensively summarized. Furthermore, the developments of VDMs are proposed. Finally, the trends and directions of VDMs and VEDs are prospected. This systematic review can encourage the research community to conduct more studies and help engineers facilitate further applications.
