• Fatigue
• Kinematic hardening
• Nonlinearities
• Saturation
• Ratcheting

To compensate the drawback of most kinematic hardening laws who exhibit hardening saturation, a solution is proposed by replacing the accumulated plastic strain rate in the springback term by a rate related to the kinematic hardening variable itself. The proposed approach defines a power-law counterpart to the linear (Prager) and exponential (Armstrong-Frederick) laws.
