Workshop on Metamaterials and Metastructures for Civil Infrastructure

基础力学、先进制造和材料科学的进步导致了一个真正突破性的新材料家族的诞生，这些新材料被称为建筑超材料。这些材料表现出天然材料所没有的行为和特性。迄今为止，与建筑超材料相关的高成本和小体积在很大程度上阻碍了它们在结构和民用基础设施应用中的采用。然而，这些材料前所未有的特性具有改变建筑环境的潜力。要实现这一潜力，需要从一个新的角度来看待建筑超材料。该讲习班将提供一个论坛，以便在不同的领导专家小组之间开展对话，并探索研究前沿。研讨会将汇集来自先进制造、材料、岩土和结构工程、建筑和设计等领域的研究人员和工业专业人士，以确定建筑结构超材料的研究机会，并提供解决这些机会的建议。该研讨会将于2021年4月在马萨诸塞大学阿默斯特校区举行。研讨会的重点将是揭示如何利用建筑超材料的基本原理来提高民用基础设施的性能，并确定基础研究的差距，同时牢记成本、耐用性、可持续性、可制造性和施工便利性等方面的限制。研讨会将探讨可扩展建筑超材料的关键未来方向。将讨论增材制造、建筑机器人和其他先进建筑制造方法的影响和利用，以确定将超材料带入建筑环境的自下而上和自上而下的策略。讲习班将以讲习班报告的形式提出建议。这些建议将传播给广大利益攸关方。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Progress in fundamental mechanics, advanced manufacturing and materials science has led to the creation of a truly groundbreaking family of new materials called architected metamaterials. These materials exhibit behavior and properties that do not occur in natural materials. The high cost and small volumes associated with architected metamaterials have thus far largely prevented their adoption in structural and civil infrastructure applications. Yet the unprecedented properties of these materials hold the potential to transform built environment. A new perspective on architected metamaterials is needed to realize this potential. This workshop will provide a forum to initiate a dialogue among a diverse and leading group of experts and to explore the research frontier. The workshop will bring together researchers and industrial professional from the communities of advanced manufacturing, materials, geotechnical and structural engineering, construction and design to identify research opportunities in architected metamaterials for structures and provide recommendations to address these opportunities. The workshop will be held at the University of Massachusetts, Amherst campus, in April 2021. The focus of the workshop will be uncovering how fundamental principles of architected metamaterials could be harnessed to enhance performance of civil infrastructure, and to identify the fundamental research gaps while keeping in mind constraints on cost, durability, sustainability, manufacturability and ease of construction. The workshop will explore critical future directions towards scalable architected metamaterials. The influence and utilization of additive manufacturing, construction robotics and other advanced construction manufacturing approaches will be discussed to identify bottom-up and top-down strategies for bringing metamaterials to the built environment. The workshop will provide recommendations in the form of a workshop report. These recommendations will be disseminated to a broad group of stakeholders.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
