Plane stress/strain thickness in ABAQUS
I have a very short question. What is the exact meaning of "plane stress/strain thickness" in ABAQUS?
It is used when section is defined for 3D models and typically takes the value of 1. I'd also like to know what difference would it make if some other value is specified. I guess, I would know that if I knew the exact meaning (or maybe not?).
Thanks in advance for your answers!
