摘要
1.引言本文讨论如下第二类变分不等式[1,2,3]的有限元逼近及其误差分析:求u∈V。
A new type of finite element scheme including the numerical integration modification is presented for the second type variational inequality. Our methods really simplify the finite element analysis and practical calculation. The unique existence and stability of finite element solution are proved , and particularly the optimal order error estimates are derived under H1 and L2 norms.
