Vibration is a common phenomenon when a structure is exposed to one or multiple mechanical or environmental actions, always at great cost to lives and to the economy. In order to reduce the adverse impact of vibration, various dampers made by different vibration mitigation materials have been widely used to bolster structural integrity. Nonetheless, the highly non-linear properties of vibration mitigation materials can tend to increase the complexity and non-determinacy of vibration mitigation. As such, it is imperative to study vibration mitigation materials and to learn how to use them within real structures. This Research Topic aims to study the mechanical behavior of different vibration mitigation materials, develop new vibration mitigation materials, design next-generation dampers, and verify the availability of vibration mitigation materials.
In the last two decades, significant contributions have been made by research groups around the world toward the development of vibration mitigation materials. Their work consists of several parts as follows:
(1) developing new vibration mitigation materials such as viscoelastic materials, viscous materials, magnetorheological materials, shape memory alloy materials, or metallic materials
(2) developing the reinforced body and matrix of vibration mitigation materials, e.g. the brominated butyl rubber matrix, silicone rubber matrix, natural rubber matrix, or chemigum matrix
(3) studying the molecular structure of vibration mitigation materials, and
(4) establishing mathematical models to express material behaviors.
Beyond vibration mitigation materials, several dampers made from vibration mitigation materials have also gained interest and have been successfully employed in real applications, for example laminated rubber bearings, lead-rubber bearings, viscoelastic dampers, viscous dampers, magnetorheological dampers, shape memory alloy dampers, shear dampers, as well as tension and compression dampers, among others.
Although much work has been published, many challenges and research themes are still open for exploration, including: how to make next-generation vibration mitigation materials with greater efficiency, how to describe the molecular structure and mathematical models of vibration mitigation materials, how to analyze the nonlinear dynamic responses of a structure reinforced with vibration mitigation materials, or how to optimize the working parameters of materials and dampers.
This Research Topic welcomes contributions addressing all aspects of vibration mitigation materials and structures geared toward solving the above questions. As such, we solicit vibration mitigation-related submissions of research papers dealing with themes that include, but are not limited to:
• Next-generation vibration mitigation materials
• Preparation and modification of vibration mitigation materials
• Mechanics description of vibration mitigation materials
• Tests on vibration mitigation materials
• Damage and fracture of vibration mitigation materials
• Parameter optimization of vibration mitigation materials and dampers
• Development and tests of dampers with vibration mitigation materials
• Parameter optimization of structures with vibration mitigation materials
• Dynamic analysis and tests on structures with vibration mitigation materials
• Applications of vibration materials and dampers
