对机械装置的整体阻尼的一个重要贡献是由于结合界面中的摩擦的微滑移效应引起的结构阻尼。为了研究这些接触界面的力学行为数值，接触单元的有限元法（FEM）的背景下。建议的单元是一个等参零厚度单元，它非常适合于本问题，因为接触面积是已知的，只有小的相对位移发生。可以实现任意线性或非线性接触模型的法向和切向接触行为。使用适当的参数化的接触面积，它是可能的，适用于接触界面中的元素在任意的空间和界面离散与变形元素。该方法是描述之前的数值例子与实验结果进行了比较。（© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
An important contribution to global damping of mechanical devices is structural damping due tomicroslip effects with friction in joint interfaces. In order to investigate the mechanical behaviour in these contact interfaces numerically, a contact element in the context of Finite Element Method (FEM) is presented. The suggested element is an isoparametric zero thickness element which is well suited for the present problem because the contact area is known and only small relative displacements occur. Arbitrary linear or nonlinear constitutive contact models for normal and tangential contact behaviour can be implemented. Using a proper parametrisation of the contact area, it is possible to apply the element in contact interfaces lying arbitrarily in space and in interfaces discretized with distorted elements. This method is described before a numerical example is compared with experimental results. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
