AmeriMech Symposium on the Dynamic Response of Periodic Materials and Structures; Georgia Institute of Technology, Atlanta, Georgia; April, 2014

摘要通过设计微结构来控制波和声响应的能力导致了线性和非线性声学超材料和声子晶体的出现。虽然人们对这一领域的兴趣越来越大，但许多研究都是在大规模或全国性的合作下进行的，主要资助机构的投入也很少。这一领域的时机非常需要将多个研究社区(动力系统、材料力学、MEMS、数学、物理等)的成员和来自主要资金来源(国家科学基金会、陆军研究办公室、海军研究办公室等)的项目经理聚集在一起，以确定需求和研究方向。认识到这一需要，研究人员将于2014年4月在佐治亚理工学院举行关于周期性材料和结构动态响应的首届ameriMech研讨会。该研讨会旨在汇聚40-50名从事周期材料和结构工作的初级和高级研究人员，以便a)分享周期结构和材料(细胞/晶格材料、声学超材料、声子晶体)的最新和新出现的发展；b)确定需要在理论、制造技术和应用方面取得新发展的领域；以及c)收集项目经理对国家需求驱动的周期结构的有前途的应用的意见。预计该专题讨论会将对周期性结构和材料领域的国家供资优先事项和研究方向产生广泛影响。参与者的陈述和小组讨论将在不同的利益相关者之间分享，目的是确定研究需求、方向和有前景的应用。NSF基金的援助将旨在通过免除研讨会注册费和支付有限的旅费的赠款，将研讨会与会者的参与范围扩大到更年轻的研究人员(助理教授和博士后研究人员)、研究生和代表不足的群体。这笔资金将补充已经从美国国家科学院美国国家理论和应用力学委员会(USNCTAM)获得的资金，以及佐治亚理工学院和不列颠哥伦比亚大学承诺的配套资金。专题讨论会的要点将以电子格式在专题讨论会网页上分享，并通过其他有关各方的请求广泛分发给与会者、同事和其他有关方面。

AbstractThe ability to control wave and acoustic response by designing microarchitecture has led to the emergence of linear and nonlinear acoustic metamaterials and phononic crystals. While there has been great and growing interest in this area, much of the research has been performed with little cooperation on a large or national scale, and with little input from major funding establishments. The timing of the field is such that a great need exists to bring together members of multiple research communities (dynamical systems, mechanics of materials, MEMs, mathematics, physics, and others) and program managers from major funding sources (National Science Foundation, Army Research Office, Office of Naval Research, and others) to identify needs and research directions. Recognizing this need, the investigators will hold an inaugural AmeriMech Symposium on the Dynamic Response of Periodic Materials and Structures at the Georgia Institute of Technology in April, 2014. The symposium aims to bring together 40-50 junior and senior researchers working on periodic materials and structures in order to a) share recent and emerging developments in periodic structures and materials (cellular/lattice materials, acoustic metamaterials, phononic crystals); b) identify areas requiring new developments in theory, manufacturing technologies, and applications; and c) gather input from program managers on promising applications of periodic structures that are driven by national needs. The symposium is anticipated to have broad impacts on national funding priorities and research directions in the area of periodic structures and materials. Participant presentations and panel discussions will be shared amongst a diverse audience of stakeholders with the intent purpose of identifying research needs, directions, and promising applications. The assistance of NSF funds will be targeted at broadening the participation of the symposium attendees to younger researchers (Assistant Professors and Postdoctoral Researchers), graduate students, and underrepresented groups via grants waiving the symposium registration fee and covering limited travel expenses. This funding will supplement funds already received from the National Academies' US National Committee on Theoretical and Applied Mechanics (USNCTAM), and matching funds committed by Georgia Tech and the University of British Columbia. Highlights from the symposium will be shared in electronic format on a dedicated symposium web page and distributed widely to participants, colleagues, and via requests from other interested parties.
