Yield functions and plastic potentials for BCC metals and possibly other materials

Richard M. Christensen

Vol. 1 (2006), No. 1, 183–200

Yield functions and plastic potentials are expressed in terms of the invariants of the stress tensor for polycrystalline metals and other isotropic materials. The plastic volume change data of Richmond is used to evaluate the embedded materials properties for some bcc metals and one polymer. A general form for the plastic potential is found that is intended to represent and cover a wide range of materials types.
