Yes i understand that Abaqus uses the creep data and converts it to relaxation data, through convolution integrals i think. Analytical Fracture Mechanics (Dover Civil and Mechanical. Dover Civil and Mechanical Engineering Theory of viscoelasticity - Richard M. 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. For analysis of experimental data has progressed substantially. I find that much more work is published on the nonlinear elasticity aspects of soft materials and potentially important time effects get missed; especially in impact loading the time element is a critical consideration. When a material exhibits a linear response it is categorized as a Newtonian material. With spherical indenters the use of linearly viscoelastic models for characterization of a material creep or relaxation function is straightforward. When you say the data is not covering a wide enough range to accurately Also, polypropylene is a non-linear viscoelastic material (as are most polymers), and modelling viscoelasticity in Abaqus in the way outlined above only encompasses a linear viscoelastic response. 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. The plate is made of nonlinear viscoelastic orthotropic material expressed by the Schapery single integral model. In addition, many materials of engineering importance exhibit significant nonlinear viscoelastic behavior in physical environments and under mechanical loading of practical interest, especially under high-temperature conditions. A recursive-iterative formulation is implemented for the hereditary integral of the material. Mechanics of Composite Materials (Dover Civil and Mechanical Engineering) 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. Finally, fit the pseudo data with the Prony series. History of viscoelastic materials. Morrison (2001), Understanding Rheology, Oxford University Press, ISBN 0-19-514166-0 and 978-0195141665. Creep and Relaxation of Nonlinear Viscoelastic Materials: With an Introduction to Linear Viscoelasticity. An age-dependent Maxwell chain model with four Maxwell elements was used to model stress relaxation and creep [41].
