  contact pairs
A finite element analysis (FEA) model defining more than 300 contact pairs for long nut-short screw locking mechanism of a large-scale vertical gear-rack typed ship-lift was built.
      
The results show that the design of the locking mechanism meets the requirement of engineering, and this method is effective for solving large scale nonlinear contact pairs.
      
Serotype patterns of gonococcal infection in contact pairs
      
Using two movable contact pairs, cross-correlation functions of flux flow noise from polycrystalline niobium and vanadium foils have been measured.
      
The data were analyzed using the Fuoss 1978 equation which is based on the coupled equilibria: (unpaired ions)?(solvent-separated pairs)?(contact pairs).

  contacting pairs
On the basis of analytic and numerical solutions, we investigate the effect of mechanical, geometric, and frictional properties of the contacting pairs on the stress-strain state of the systems under consideration.
      
A higher content of hard phase leads to brittle failure of the hardened layer and an increased content of plastic phase to seizing of the contacting pairs.
      
For simplicity, we assume that the interface contacts and hence the coordination numbers for all contacting pairs remain unchanged.

Several conventional contact searching algorithms, with the advantage of excellent computational efficiency, are usually refer to lower order finite element. But which are not suitable for the contact problems in which higher order finite element is adopted. It has an urgent need in engineering that developes a kind of contact searching algorithm which can deal with the contact problems of higher order FE and its computational efficiency has equal level to conventional contact searching algorithms. On the basis of the Systematic Search Method and nonlinear constrained optimization theory, this paper developes a new kind of contact searching algorithm of higher order finite element. A variety of examples show that the contact searching algorithm has better computatinal efficiency and higher precision.

Three criteria of contact searching and a pre -contacting search method are suggested in this paper. Through pre - contact searching, a great deal of surface finite elements is eliminated from a wider scope of the contact-pairs to be searched. An automatic contacting search algorithm of dynamic analysis for the lower order finite element is presented. The new algorithm for the lower order FE is based on the Master surface-Slave node concept and the closest point projection search method. It has the advantages of generating candidate contact elements automatically, relieving users from tedious input for contact interfaces. Numerical experiments show that the algorithm is reliable and efficient.

本文基于三个接触搜索准则提出接触预搜索概念。在接触预搜索阶段通过分级筛选方法逐步缩小可能接触点副的单元集;然后,给出动态有限元分析中适用于大滑移的低阶单元接触点副的自动搜索算法。针对非线性动态接触问题有限元分析中常用低阶单元和点-面模式的搜索方式的情况,本文应用最近点投影搜索算法提出以等参坐标为参数的另一种接触搜索算法。该搜索算法不须预先指定可能接触范围,从而极大地降低了数据的准备工作和出错率;本搜索算法将各种可能接触状态统一在一种算法中进行处理,不必对各种接触状态分别采用不同的算法。算例表明,本文给出的低阶单元接触搜索算法是有效和可靠的。
