连杆接触单元非线性模型及其工程应用

Non-Linear Model of Rod Contact Element and Its Engineering Applications

在连杆接触单元非线性模型的基础上，增加了有初始间隙的摩擦接触问题的闭合本构关系，算例及工程应用表明，本模型理论正确，计算结果合理且精度较高，并易于实施。

A non-linear model of rod contact element is presented by the author. The closing constitutive relation for the frictional contact with initial gap is added to the model in this paper, which makes it more perfect. An example and an engineering application show that the theory of the model is correct, its computed results are reasonable and of high accuracy. And the model is easy to apply, making it a powerful tool in solving complex engineering contact problems.
