在有限元表示中使用的位移场被用来获得平面应力问题的极限载荷的上界。这些上限很容易被最小化，并提供良好的估计的崩溃负载。所得结果与弹塑性有限元分析结果吻合较好。对计算机存储和时间的需求很小。
Displacement fields used in finite element representations are used to obtain upper bounds to the limit loads of plane stress problems. These upper bounds are readily minimized and provide good estimates of the collapse load. The results obtained are in good agreement with those given by elastic-plastic finite element analysis. The demand on computer storage and time is small.
