向版主及各位高手们请教一个节点解的问题
我在做ansys后处理时,列表显示节点内力结果时,(单元类型为shell63)发现几乎每一个节点都出现了很多个解,请问这是什么原因呢?应以哪个解为准呢?希望大家说一说,给我们指点迷津! 显示不同侧的解。 venture的回答不够确切吧？ 应该说不同方向和不同的应力准则下的解？
建议楼主先复习一下材料力学中的应力应变相关的内容。 原帖由 心灯 于 2007-1-18 19:00 发表
venture的回答不够确切吧？ 应该说不同方向和不同的应力准则下的解？
建议楼主先复习一下材料力学中的应力应变相关的内容。
:lol 是不够确切，应该说是：
1. 每个节点列出了2行应力，分别为壳内侧和外侧的解。
2. 每行中列出了节点X,Y,Z,1,,2,3,SINT,VON等等应力。 具体以那个为准，要看你结构要求的判断准则，一般来说用von，但是如果是压力容器一般用sint（还要进行应力线性化处理）。 原帖由 venture 于 2007-1-19 09:44 发表

首先对大家的回贴thank you一下!
在经检查模型没错的情况下,我列表显示节点应力时,有的节点,同一个编号出现了6行不同的值,有的出现4行,也有2行的,不懂出现6行应力值时,又是具体关于什么的解呢?我是用来做静态电测实验的,应该取哪一行的应力值为准呢?
如果不同行的应力值是表示不同侧的解的话,那么哪一行对应于哪一侧呢?
希望大家讨论以解惑! 请指点!
[ 本帖最后由 dengtengshu 于 2007-1-19 16:46 编辑 ] 把你的结果贴出来看看，静态电测试验一般取外侧，如果做单向应力的话要取相对应方向上的应力。

同一节点出现多行不同解的情况如下:请各位老大观摩,讨论,指教,如果表示不同侧面的话,哪一行与哪一个侧面对应!

请各位老大继续讨论,以求给我们一个清晰答案
请各位老大继续讨论,以求给我们还不了解这些的人一个清晰答案!thank you! 我也很想知道！答？
谢谢了~~~ 还有，各级老大，老师们，呵呵，我还想请问：
1、element table中的值又是怎么计算出来的呢？是每个单元的积分点上的平均值？
2、Nodal Calcs中的Sum@each node与Nodal solution中的解有什么不同？
搞了很久没搞清楚:@L
望高人指点
