Creep describes a time and temperature dependent plastic deformation under a constant force. When a constant force is applied to a rubber compound, the initial deformation obtained due to the application of the force is not fixed. The deformation will increase with time. Creep takes place!
Creep behavior is the term for describing the creep processes taking place in different materials.
Depicted in the figure are the characteristics of a high-stress and low-stress creep curve. The figure shows creep over time.
