The kinematic relationship between classical single crystal kinematics and geometrically necessary dislocations will be clarified by a demonstrative example. The starting point for the dynamics is the contribution of geometrically necessary dislocations to the free energy, which leads to a kinematic hardening law. A simple two‐dimensional shear example will be discussed. (© 2010 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
