摘要
En 中文
A kind of improvement contact frictional model based on traditional Coulomb friction model is adopted. Corresponding contact element also is given. Detail contact algorithm based on sequential quadratic programming (SQP) and augmented Lagrange method is introduced and applied on complex contact friction problem successfully. The results of test example and the actual engineering case all show that the algorithm of the model is efficient. (C) 2007 Elsevier Inc. All rights reserved.
