Drained and Undrained Condition
Drained and Undrained Condition
(OP)
Can some one please explain me in simple terms what the difference between drained and undrained condition is? And for sand and clay what conditions to use? Specially for sand since the parameters dont change a lot for the two conditions which one do you use when performing finite element analysis





RE: Drained and Undrained Condition
There's just too much engineering judgement to answer your second question. I have no idea what parameters to use when conducting a finite element analysis because I don't know what you are trying to model.
Good luck. Maybe if there was further insight to your problem we could help.

RE: Drained and Undrained Condition
As for which to use, answer this: What kind of loading condition are you trying to model? If the condition happens quicker than the soils can drain, use undrained. If the condition happens slower, use drained. It is common to do analysese both way if the loading can happen both ways. Also, as fattdad pointed out, unless it is an earthquake it is unlikely that the sand will not be drained.
