A decrease in stress due to creep is known as which term?

Explanation:
Relaxation is the time-dependent decrease of stress under sustained deformation. When a material is held under load, creep causes it to deform gradually, and the internal stresses tend to redistribute and diminish over time. In prestressed concrete, this shows up as a loss of prestress force as the tendons and surrounding concrete creep, so the initial stress level drops with time. The other terms don’t describe this behavior: residual camber is the leftover curvature after release, and resurfacing or relief aren’t standard terms for stress decay due to creep.
