In this paper, potentials that analytically describe the plastic behavior of orthotropic metals are reviewed. These potentials, yield functions or strain rate potentials were expressed in six-dimensional stress or strain rate spaces, respectively. Some of the recently developed potentials that are consistent with polycrystal plasticity models are briefly discussed and applied to computational analysis and design of sheet metal forming processes.
