请教ADINA几个问题：接触面单元编程、REBAR结构单元物理属性设置

请教大侠下面接触面单元程序的含义：

还有不知道REBAR单元物理属性如何设置，请高手指教，不甚感激！

哪位乡亲帮帮忙啊，小弟给乡亲们跪下来了！！急啊……

baishi1226 发表于 2006-12-3 13:16:00

难道就没有人会吗？？奇怪了！帮帮忙啊！我关键接触面方向我不会设置

ecty 发表于 2006-12-3 18:53:45

一般情况，默认值就可以了，摩擦系数可以根据情况设定，土木手册里有例题可以参考的

zhufangcai 发表于 2008-4-4 15:44:52

不能用GOODMAN单元，接触问题只能用库仑摩擦及自定义摩擦。

mincq 发表于 2009-3-19 10:13:43

ADINA 的接触问题似乎很模糊，我一直在找，都没有找到权威的解答，尤其是rebar的接触

junyao365 发表于 2009-3-19 10:50:09

过几天我也要找了要用到接触
