AN INVESTIGATION INTO THE COMBINED ISOTROPIC-KINEMATIC WORKHARDENING RULE

The Ziegler modification of the Prager kinematic workhardening rule has been shown to be a correct statement of consistency during plastic loading. Although the same modification has been used in conjunction with a combined isotropic-kinematic workhardening rule, it has not been established that this latter model renders an acceptable statement of consistency. This paper shows that the Ziegler modification used with the combined isotropic-kinematic workhardening rule not only satisfies the consistency condition, but is also computationally more efficient than a direct employment of the consistency condition.
