本文推广了Xue和Cheng [L. Xue，X.L.程，一种解决障碍问题的算法，Comput。Math.Appl.48（2004）1651-1657]，用于解决双障碍问题。本文试图用迭代的方法，以较少的计算时间找到双障碍问题中接触的近似区域。最后给出了弹塑性扭转问题双障碍问题的数值算例。
In this paper, we extend the algorithm in Xue and Cheng [L. Xue, X.L. Cheng, An algorithm for solving the obstacle problems, Comput. Math. Appl. 48 (2004) 1651–1657] for solving the double obstacle problem. We try to find the approximated region of the contact in the double obstacle problem with less computation time by iteration. Numerical example is given for the double obstacle problem for the elastic–plastic torsion problem to support the algorithm.
