在帮助文档里找见这样的话,可以说明一下问题的解决方法:
How do I obtain stress/force results for 1-D elements?
For CBAR/CBEAM elements, normal stress at the cross-section origin is output by default, and is controlled by the STRESS I/O option. If stress results are desired for other locations, the first continuation line for the PBAR/PBEAM definition is required. The maximum stress calculated at any of the four allowable stress recovery locations is then reported as the element's axial stress.
Sectional forces and moments for 1-D elements can be obtained through the FORCE I/O option. If FORCE=YES is added to the I/O options section of the input deck, the .force file is output containing force and moment results.
The stress recovery coefficients C1 and C2, etc., are the y and z coordinates in the BAR element coordinate system of a point at which stresses are computed. Stresses are computed at both ends of the BAR.
在定义property的时候需要定义C1,C2,D1,D2,E1,E2,F1,F2,这样就可以输出了,输出的应力为其中最大的应力。还是得好好看帮助文件!
另外,在定义后比较PBAR和PBARL两种属性定义的计算结果相差很大,PARL计算结果有误,目前正在寻找原因中,有哪位知道指点一下,谢谢了! |
