Bounding surface plasticity model with extended Masing behavior
The author formulates a deviatoric bounding surface plasticity model that preserves Masing's rule, and an algorithm that allows for the lack, or for the existence, of an elastic range. The material-specific parameters can be obtained directly from tests. A mapping converts monotonic isotropic hardening functions into anisotropic ones that depend on the previous loading history. The cyclic behavior resembles that of the nested yield surface models, the cycles are stabilized from the first loop. The unloading curve preserves a fixed homological ratio of two, with the initial monotonic one and the process reloads through previous hardening functions when the corresponding stress-strain curves are intersected.
