Hi

From what I read, my first reaction would be to say "Yes", and to compare the results, perhaps in steps starting with smaller loads to follow the on-linear the trend.

And, in anycase I can only suggest that you also do a couple of simplified hand calculations to check that your results seems correct.

Good luck

Hi Ivar,
I that case are you saying that the large deformation on is mainly used when the results are non linear?

Assuming that I have a pre-stress condition that will linearize the results should I still use the Large Deformation on?

And lastly, in my condition if I have a circular membrane of 8 micron thickness and a 1 mm radius and clamped at the circumference, should I still set the large deformation to be on or off? I am still new at this and the manual does not seem to suggest on how shall I deal with this issues.

Hope that you could help in this matter.

Hi

for me (in my understanding) I use large deformation for non-linear effects to get the cross elements 2nd order of the deformation in the calculations (see the structural doc)

but if I have a doubt (and in anycase wile setting up my models I work first WITHOUT large deformations as it's much quicker to solve) I run a "large deformation" case at the end, just to compare my results, in case of large diferences, I investigate further

Hi
I would like to ask , set the large deformation switch where? or how to set the large deformation of the vertical cantilever beam?

Thank you in advance!
