Abstract
Material models in FE-simulations are used both in 3D and plane stress situations. In this
paper it is shown that for models that include kinematic hardening, the conversion from a 3D to a plane
stress algorithm needs more adaptations than only eliminating the thickness components. An example
and a consistent conversion are presented. Secondly it is discussed how to convert a 2D plane stress
yield criterion into a full 3D yield criterion. This is essential for using solid-shell elements with 2D yield
criteria, typically used in sheet metal forming
