摘要
研究了由椭圆变分不等式描述的弹塑性扭转问题,构造了基于Uzawa算法的局部微分求积法,给出了数值算例,通过与有限元方法的比较,说明了方法的有效性。
The elastic-plastic torsion problems described by an elliptic variational inequality are discussed in this paper.It presents the local differential quadrature method based on the Uzawa algorithm.Finally some numerical experiments are given,comparing with results of FEM,it shows that Uzawa-LDQ method performed better than FEM regarding accuracy,efficiency and computing time.
