Response of the material, as well as on the creep behavior following strain controlled form the relaxation boundary which resembles a nonlinear stress-strain curve. Finally, fit the pseudo data with the Prony series. Depending on the change of strain rate versus stress inside a material the viscosity can be categorized as having a linear, non-linear, or plastic response. History of viscoelastic materials.

Et al., Creep and Relaxation of Nonlinear Viscoelastic Materials , 1990. When a material exhibits a linear response it is categorized as a Newtonian material. G., Nonlinear Mechanics , 1998. Dover Civil and Mechanical Engineering Theory of viscoelasticity - Richard M. And Munz, D., Stress Intensity factors and Weight Functions , 1997. 2.2.1 Viscoelastic Constitutive Models . The plate is made of nonlinear viscoelastic orthotropic material expressed by the Schapery single integral model. Once the parameters of the creep model are known, produce relaxation pseudo-data with the conjugate relaxation model for the same times of the original data.
