Before revision: The picture shows dependence of dimensionless stress upon dimensionless time : Dependence of dimensionless stress upon dimensionless time under constant strain If we free the material at time , then the elastic element will spring back by the value of Since the viscous element would not return to its original length, the irreversible component of deformation can be simplified to the expression below: Effect of a sudden stress If a Maxwell material is suddenly subjected to a stress , then the elastic element would suddenly deform and the viscous element would deform with a constant rate: If at some time we would release the material, then the deformation of the elastic element would be the spring-back deformation and the deformation of the viscous element would not change: The Maxwell model does not exhibit creep since it models strain as linear function of time.
