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，通过对复杂的连接结构的动力学行为以及相关的界面力学的研究，在理解其行为方面取得了重大进展。这些结构无处不在，不仅在基础设施系统中，而且在所有制造部件和系统中，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，通过在一系列尺度上结合分析、计算和物理实验的研究方案，已经取得了重大的理解。然而，一个完整的预测方法的概念，分析复杂的，关节结构，采取微观尺度的测量，如当地的材料和表面性能在关节界面和返回准确的宏观尺度参数，如当地的刚度和阻尼仍然难以捉摸。这项建议寻求资金，以支付讲习班的部分组织和现场费用以及一些国际与会者的旅费。桑迪亚国家实验室将提供额外的讲习班资金以及国内与会者的旅费援助。更广泛的影响：讲习班将因其与会者的技术多样性而独一无二。将确定一部分年轻的研究人员，特别是来自代表性不足群体的研究人员，并鼓励他们参加和参与制定研究路线图。讲习班成果的广泛传播将吸引新一代的工程师和科学家研究这类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.
