Abstract We discuss the weak form of the Ramberg/Osgood equations (also known as the Norton/Hoff model) on two‐dimensional domains and prove continuity of the stress and the strain tensor. These equations are of great importance since they can be used as an approximation for elastic‐perfectly plastic Hencky materials.
