基于增强型拉格朗日法的接触模型及其工程应用

摘要

A kind of improved contact frictional model on basis of traditional Coulomb Friction model is adopted.Corresponding contact element is also given. The contact algorithm on basis of augmented Lagrange method is introduced and successfully applied to complex contact friction problem. Test example and actual engineering case all show that the algorithm of the model is efficient and computation results agree well with general rules.
