Jointed structures are pervasive throughout manufactured systems and their presence in high consequence applications (such as in aerospace, defense, and civil infrastructure) has been tied to high profile failures that have cost billions of dollars per year. Therefore, the prediction of the interfacial stiffness, dissipation and nonlinear response of a jointed connection is one of the greatest challenges in structural dynamics. Over the past several years, the efforts of researchers in this important area have been focused and coordinated through a series of triennial workshops. Significant advances have occurred during this period both in macro- and micro-scale modeling and experimentally characterizing joints, and these workshops have been especially valuable in coordinating the efforts across various disciplines and countries. The upcoming workshop of this series will be held in October 2015, in Dartington, UK. This award will help offset the costs of travel for researchers and graduate students from the United States.The workshop will bring together researchers from academia, major laboratories, and industry, as well as representatives from European funding agencies. Research funding in the United States on dynamics of jointed structures currently lags that in the European Union. This workshop will allow US researchers to be exposed to competing/complimentary methods in more depth than is possible in a conference setting and will stimulate collaboration. This will ensure that research focuses on the areas of broadest impact, and will enable the assessment of progress towards grand challenges. Specific topics that will be promoted by US researchers participating to the workshop include implementation/integration of prediction methods in finite element codes, formulation of a round robin/benchmark exercise for measurement and prediction of dissipation in standard joints , and the investigation of epistemic and aleatoric uncertainty modeling and measurements.

接合结构在整个制造系统中普遍存在，它们在高后果应用（例如航空航天、国防和民用基础设施）中的存在与引人注目的故障有关，每年造成数十亿美元的损失。因此，预测关节连接的界面刚度、耗散和非线性响应是结构动力学中最大的挑战之一。在过去的几年里，通过一系列三年一度的研讨会，研究人员在这一重要领域的努力得到了集中和协调。在此期间，宏观和微观尺度建模以及关节实验表征方面都取得了重大进展，这些研讨会对于协调不同学科和国家的努力特别有价值。该系列即将举行的研讨会将于 2015 年 10 月在英国达廷顿举行。该奖项将有助于抵消来自美国的研究人员和研究生的旅行费用。研讨会将汇集来自学术界、主要实验室和工业界的研究人员以及欧洲资助机构的代表。美国在连接结构动力学方面的研究经费目前落后于欧盟。该研讨会将使美国研究人员比在会议环境中更深入地接触竞争/互补方法，并将促进合作。这将确保研究重点关注影响最广泛的领域，并将能够评估应对重大挑战的进展。参加研讨会的美国研究人员将推动的具体主题包括有限元代码中预测方法的实现/集成、标准接头耗散测量和预测的循环/基准练习的制定，以及认知和任意的研究不确定性建模和测量。
