State the term - Relaxation of Stress in Steel

If we keep a high-tensile steel wire stretched and maintained at a constant strain, the value of the force in the wire does not remain constant but reduces with time. This phenomenon is called as relaxation of stress in steel. Due to relaxation of stresses in tendons, loss of prestress takes place in prestressed concrete members. The values of loss of prestress because of relaxation of steel are specified in the code.
