摘　　要：The finite element methods for the second type variational inequality deduced from the simplified contact problem with friction have been considered by R.Glowinski et al [2]. In this note, the modified finite element method with numerical integration for this problem is considered, and the error estimate is improved.The finite element methods for the second type variational inequality deduced from the simplified contact problem with friction have been considered by R.Glowinski et al [2].
