结构塑性区域图的一种有效绘制方法

An Efficient Method for Drawing Plastic Zones of Structures

提出了一种结构塑性区域图的有效而简单的绘制方法，根据弹塑性有限元的计算结果，采用有效的搜索策略，在结构边界和内部连续搜索塑性区域轮廓的高斯积分点，并用一定的方法连结起来，生成。ＳＣＲ命令组文件，通过ＡｕｔｏＣＡＤ绘图软件包，计算机自动生成结构塑性区域图，并显示已进入塑性状态的高斯点位置。实例表明，该方法所绘制的图形清晰。

An efficient and simple method to draw plastic zones of loaded structures is presented.An effective tactic has been adopted to continuously search for a series of Gaussian integration points on the edges of plastic zones based on the results obtained by using elasto-plastic FEM.These points are joined then,docurments of SCR command group are automatically gnerated.The graphics of the plastic zones of the structure and the locations of plastic Gaussian integration points can automatically be displayed on the screen when the method is used with AutoCAD.Examples show that the graphics are clear and the method is efficient.
