Difference between isotropic and kinematic hardening? What does translation of yield surface mean?

Question

Accepted Answer

Isotropic hardening refers to the change in yield stress due to plastic deformation, while kinematic hardening refers to the change in yield stress due to cyclic loading. Translation of yield surface refers to the shift of the yield surface in stress space.

Isotropic hardening is associated with the change in yield stress due to plastic deformation.
Kinematic hardening is associated with the change in yield stress due to cyclic loading.
Translation of yield surface refers to the shift of the yield surface in stress space.
Isotropic hardening is independent of the loading history, while kinematic hardening depends on the loading history.
Isotropic hardening is commonly observed in materials like metals, while kinematic hardening is more prevalent in soils and rocks.
