Stress relaxation is the phenomenon

Stress relaxation is the phenomenon Correct Answer In which deformation tends to loosen the joint and produces a stress reduced

Stress relaxation is a gradual reduction in stress with time at constant strain.
Stress relaxation occurs in polymers when they are held in a strained state for long periods of time.
These alloys have very good resistance to stress relaxation and are therefore used as spring materials.
