A Finite Element Solution for Frictional Sliding Contact between Hyper-elastic and Rigid Bodies

摘要：

　　This paper is devoted to the analysis of frictional contact problems with large deformations and displacements between hyper-elastic body and rigid body.The material nonlinearity and contact nonlinearity are separated and, the geometrically nonlinear behavior is described by the total Lagrange formulation.The Coulomb friction law is employed to simulate the friction between rigid vessel and rubber by the use of augmented Lagrange approach with node-to-segment formulation.A formulation of finite element is taken in this paper to describe the frictional contact problem, which is solved by the Newton-Raphson iterative procedure.It is shown that the augmented Lagrange technique significantly avoids locking and over-constraining and provides optimal convergence rate.Finally, the numerical results show that the accuracy and efficiency of augmented Lagrange approach in modeling large deformation frictional contact problem.
