理解和建模的问题，在典型的结构在动态载荷条件下的接口的动作和响应的复杂物理基础已经占据了研究人员几十年。这本手册提出了一个综合的方法，以典型的关节结构的动态建模的目标，开始与实验或模拟数据的数学评估，本构模型的发展，以占负荷历史变形，建立运动模型耦合到连续模型，并应用有限元分析导致动态结构模拟。此外，配方进行了讨论，以减轻非常短的模拟时间的步骤，似乎需要在数值模拟的问题，如这。本手册满足了对能源部的承诺，即桑迪亚将开发技术内容并编写联合手册。内容将包括：（1）机械系统和构件中典型连接的非线性刚度和能量耗散的表征方法。(2)该方法将包括实验的实际指导，以及可用于表征关节行为的降阶模型。(3)将提供典型螺栓和螺钉连接的示例。
The problem of understanding and modeling the complicated physics underlying the action and response of the interfaces in typical structures under dynamic loading conditions has occupied researchers for many decades. This handbook presents an integrated approach to the goal of dynamic modeling of typical jointed structures, beginning with a mathematical assessment of experimental or simulation data, development of constitutive models to account for load histories to deformation, establishment of kinematic models coupling to the continuum models, and application of finite element analysis leading to dynamic structural simulation. In addition, formulations are discussed to mitigate the very short simulation time steps that appear to be required in numerical simulation for problems such as this. This handbook satisfies the commitment to DOE that Sandia will develop the technical content and write a Joints Handbook. The content will include: (1) Methods for characterizing the nonlinear stiffness and energy dissipation for typical joints used in mechanical systems and components. (2) The methodology will include practical guidance on experiments, and reduced order models that can be used to characterize joint behavior. (3) Examples for typical bolted and screw joints will be provided.
