Response <strong>for</strong> cyclic loading<br />
Isotropic hardening: <strong>the</strong> yield stress is higher as <strong>the</strong> cyclic loading progresses<br />
Kinematic hardening: <strong>the</strong> difference between unloading stress <strong>and</strong> new yield<br />
stress in <strong>the</strong> opposite direction <strong>of</strong> loading is constant <strong>and</strong> equal to 2σ y.<br />
