弹性力学平面问题的十字构架模式

Cross Framework Model Solving Plane Stress Problems with Mechanics of Elasticity

对已有的正方形单元十字构架模式作了修正，推导了矩形单元十字构架模式的特性参数，并通过算例验证了它们的收敛性质．

The existing square element cross framework pattern is modified.The characteristic parameters of the rectangular element cross framework pattern are derived.And by means of calculation examples,their convergence characters are verified.
