Oh, yes you are right. But the OOP strain was exact same even without using those transforms. The z coordinate was kept the same in both cartesian and cylindrical coordinates.
Plane stress elements have displacement (U3) in the third direction. The elements I am using don't have that displacement, so they are definitely plane strain. I queried the element type as well from the ODB file. It is CPE8P. It's a 2D model, and I haven't applied any coordinate...
I am running a 2D model with CPE8P elements. These are 8 noded elements, plane strain, having pore pressure degree of freedom. Ideally there shouldn't be any out of plane (OOP) strain (E33) in these elements. But I am observing OOP strain. Can anyone provide an explanation as to why this is...
