Viscoelasticity
A combined solid-like and liquid-like behavior in which the stress-strain
relationship is time dependent.
Linear viscoelasticity
A viscoelastic behavior in which the ratio of stress to strain is a function of
time alone and not of the stress magnitude.
Stress relaxation
Decay of stress. with time when the material is suddenly deformed to a
given deformation-constant strain.
Relaxation time
The rate of stress decay in- a material subjected to a sudden strain. It is
the time required for the stress in the Maxwell model, representing stress
relaxation behavior, to decay to 1 / e or approximately 37 percent of its original
value.
