Enhanced strain formulation for plane strain 2D analysis
I started another discussion yesterday on the same analysis, but this time the problem is
slightly different: i have a 2D geometry and i want a plane strain state. I click on the "plane strain" window as in the following figure
But after that on the result i still get a Z strain.
I read on the "solution information" that my element (PLANE182) has KEYOPTION(1)=2 which means "Enhanced strain formulation" which occasionally add a degree of freedom to avoid shear Locking.
Well, what if the strain along Z is due to the addition of UZ DOF?
If yes, how can i solve this problem? I just want Plane strain from my solution, that's the objective.
Thank in advance! I will appreciate any help
