History of viscoelastic materials. 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. Bland, The Theory of Linear Viscoelasticity, New York: Pergamon Press, 1960. 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. Aleksey Drozdov and AlDorfmann [2] derive constitutive equations for the nonlinear viscoelastic behaviour after performing tensile relaxation tests. Abstract This paper is concerned with the development of a new incremental formulation in the time domain for linear, non-aging viscoelastic materials undergoing mechanical deformation. Section 3 deals with the problems associated with the determination of the Constitutive Equation of nonlinear viscoelastic materials. Dover Civil and Mechanical Engineering Theory of viscoelasticity - Richard M. Wave Motion, Poro-Elasticity Problems and Constitutive Equation of Materials. An age-dependent Maxwell chain model with four Maxwell elements was used to model stress relaxation and creep [41]. When a material exhibits a linear response it is categorized as a Newtonian material. Elements for the Numerical Analysis of Wave Motion in Finally a method is presented for the comparison and evaluation of the consistency of creep and relaxation data obtained by a set of independent experiments. Most of analytical [6-7] have applied the incremental formulation in order to evaluate creep crack growth process in viscoelastic media.

Finally, fit the pseudo data with the Prony series.
