题目：From Muscles to Plants – Nature-Inspired Adaptive Metamaterials
During the past few decades, due to the advances in materials, electronics, and system integration technologies, structural dynamics and controls researchers in various engineering disciplines (e.g., aerospace, civil, mechanical) have been investigating the feasibility of creating adaptive structures. The vision is to develop multifunctional structural systems that have various embedded and distributed autonomous functionalities, such as shape reconfiguration and morphing, materials and mechanical property variations, energy harvesting, vibration and stability controls, and health monitoring and healing. From a structural system point of view, one of the major challenges is on how to best synthesize the cross-field and local-global coupling characteristics of the various adaptive materials and elements to optimize the overall structural performance. It has been recognized that to achieve significant new advances in adaptive structures, researchers should conduct even more cross talks among various fields and disciplines. In recent years, interesting approaches have been explored to develop mechanical metamaterials based on synergistic modular architectures, often observed in nature, such as in biological systems. This presentation will discuss some of the recent interdisciplinary research efforts in synthesizing nature-inspired adaptive metamaterials for structural dynamics enhancement and applications.
