Second Workshop on Predictive Methods of Analysis for Complex Jointed Structures

人们对复杂的、连接结构的动态行为的理解已经取得了进展。 由于连接元件之间的滑动和冲击，结构是强烈的非线性和时变的;然而，它们可以在所有制造的部件和系统中找到。 主要通过美国和欧洲的研究项目，通过在一系列尺度上结合分析、计算和物理实验，取得了重要的理解。 尽管如此，对于复杂的、连接的结构的完全预测分析方法的概念仍然难以捉摸。 2006年10月，在弗吉尼亚州的阿灵顿，由美国国家科学基金会和桑迪亚国家实验室主办的一个成功的研讨会讨论了关节建模问题。 第二次研讨会拟于2009年4月27日至29日在英国举行，主要有两个目标：（1）指导先进建模的发展，以便对工程结构中使用的接头和界面的动力学进行可靠的预测;（2）探索和开发使用新分析方法的接头设计新概念，以降低不确定性和可变性。这样做的好处是结构可靠，对动态载荷的抵抗能力得到提高。 经济方面的问题将得到解决，反映出改进的设计方法将导致经济和技术的改进。 由于与会者的多样性，讲习班将是独一无二的。 将鼓励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参加并参与研究路线图的制定。 研究结果的广泛传播将吸引研究人员研究这一具有挑战性的问题。

There has been progress toward understanding dynamic behavior of complex, jointed structures. Due to slip and impact between joint elements, structures are strongly nonlinear and time-varying; yet, they can be found across the full range of manufactured components and systems. Significant understanding has been achieved principally through research programs in the US and Europe by combining analysis, computation and physical experiments over a range of scales. Still, the notion of fully predictive methods of analysis for complex, jointed structures remains elusive. A successful workshop addressing the issue of joints modeling, sponsored by the National Science Foundation and Sandia National Laboratories, was held in October, 2006, in Arlington, VA. A second workshop is proposed, in the UK, during the period April 27-29, 2009, having two major thrusts: (1) guide the development of advanced modeling allowing reliable prediction of the dynamics of joints and interfaces used in engineering structures; and (2) explore and develop new concepts for joint design using new analysis methods to achieve reduced uncertainty and variability. The benefit will be reliable structures with improved resistance to dynamic loads. Economic aspects will be addressed reflecting the belief that improved design methods will result in both economic and technical improvements. The workshop will be unique by virtue of the diversity of its participants. A subset of younger researchers, particularly those from underrepresented groups, will be encouraged to attend and participate in the development of the research road map. Broad dissemination of results will attract researchers to this challenging problem.
