NSF - Sandia National Laboratories Workshop on Predictive Methods of Analysis for Complex Jointed Structures

摘要CMS 0646122在过去的几十年里，通过研究复杂节理结构的动力学行为以及相关的界面力学，在理解复杂节理结构的行为方面取得了重大进展。这些结构不仅在基础设施系统中无处不在，而且在所有制造的部件和系统中都是如此，其中一些对国防至关重要。世界各地的研究人员，特别是美国、欧洲和亚洲的研究人员，通过各种尺度上的分析、计算和物理实验相结合的研究计划，已经取得了重大的理解。然而，对于复杂的节理结构的完全预测性分析方法的概念仍然是难以捉摸的，该方法采用节理界面上的局部材料和表面属性等微观尺度可测量的量，并返回诸如局部刚度和阻尼等准确的宏观尺度参数。这项提议寻求资金，以支付讲习班的部分组织和现场费用以及若干国际与会者的旅费。讲习班的额外资金以及国内与会者的旅费将由桑迪亚国家办事处提供。广泛影响：由于参加者的技术多样性，讲习班将是独特的。将确定并鼓励一批较年轻的研究人员，特别是来自任职人数不足的群体的研究人员参加和参与研究路线图的制定。讲习班成果的广泛传播将吸引新一代工程师和科学家关注这一非常有趣和具有挑战性的技术问题。

Abstract CMS 0646122Over the past several decades, there has been significant progress toward understanding the behavior of complex, jointed structures through study of their dynamic behavior as well as the related interface mechanics. These structures are pervasive, not only in infrastructural systems but also across the full range of manufactured components and systems, some of whichare crucial to the national defense. Significant understanding has been achieved by researchers throughout the world, and particularly in the United States, Europe and Asia, through research programs combining analysis, computation and physical experiments on a range of scales. However, the notion of a fully predictive method of analysis for complex, jointed structures,taking micro-scale measueables such as local material and surface properties at the joint interface and returning accurate macro-scale parameters such as local stiffness and damping remains elusive. This proposal seeks funding to underwrite a portion of the organizational and on-site expenses of the workshop as well as the travel expenses for a number of international participants. Additional workshop funds, as well as assistance for travel of domestic participants, will be provided by the Sandia National Labs.Broader Impacts: The workshop will be unique by virtue of the technical diversity of its participants. A subset of younger researchers, particularly those from underrepresented groups, will be identified and encouraged to attend and participate in the development of the research road map. Broad dissemination of the results of the workshop will draw a new generation of engineers and scientists to this very interesting and challenging class of technical problems.
