ABAQUS如何画XY曲线图3..doc

D.11.2?Combining the data objects In this section you will create a stress versus strain data object by combining the stress versus time and strain versus time data objects. To combine the data objects: In the Results Tree, double-click the XYData container. From the Create XY Data dialog box that appears, select Operate on XY data and click Continue. An Operate on XY Data dialog box appears. The dialog box contains the following lists: The XY Data field on the left contains a list of existing X–Y data objects. The Operators field on the right contains a list of all the possible operations you can perform on the data objects. From the Operators field, click combine(X,X). combine( ) appears in the expression text field at the top of the dialog box. In the XY Data field, drag the cursor across both the Strain and the Stress data objects to select both and click Add to Expression near the bottom of the dialog box. The expression combine(Strain,Stress) appears in the expression text field. In this expression Strain will determine the X-values and Stress will determine the Y-values in the combined plot. From the buttons along the bottom of the Operate on XY Data dialog box, click Save As. From the Save XY Data As dialog box that appears, enter the name Stress-Strain and click OK. The new data object Stress-Strain appears in the XYData container. Cancel the Operate on XY Data dialog box. 以上部分讲的就是如何利用已有的应力时间,应变曲线得到应力应变曲线了 (1)在右侧函数栏中单击一下功夫combine() (2)在函数栏左边的变量列表中双击一下XYDATA_STRAIN (3) 在函数栏左边的变量列表中双击一下XYDATA_STRESS (4)单击下面的SAVE AS按钮起个名字,关闭该对话框 (5)双击图中阴影部分就可以了 D.11.3?Plotting and customizing the stress-strain curve You will now use the Stress-Strain data object that you just created to plot the stress-strain curve. 这部分讲的就是如何给应力应变曲线设置标题,栅格以及如何从应力应变曲线中获得曲线上某点的数值并保存到文件中去,看看就可以了,很简单的. To plot the stress-strain curve: In the XYData container, double-click Stress-Strain. A plot of the stress-strain curve appears in the viewport. Your plot of stress versus strain inherited
