E33 in plane stress problem with CPS4 elements

[RGX124]

Hello,

Could you confirm that the plane stress formulation of Abaqus does not allow to obtain the out of plane strain E33?
Is the plane stress problem well implemented in Abaqus, because I get always E33=0?
This is opposite to the theory especially if Trace(Stress) differs from 0.

Thanks in advance for your answers.

Hello there,
Does anyone have an answer about the E33=0 problem with CPS4 element (plane stress)?
Thank you for your ideas and opinions about this issue.
