When a material exhibits a linear response it is categorized as a Newtonian material. 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. 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.

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. Bland, The Theory of Linear Viscoelasticity, New York: Pergamon Press, 1960. Orange relaxation curve in Figure 5 (6) This model can explain the complicated relaxation. For analysis of experimental data has progressed substantially. 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. With spherical indenters the use of linearly viscoelastic models for characterization of a material creep or relaxation function is straightforward. Aleksey Drozdov and AlDorfmann [2] derive constitutive equations for the nonlinear viscoelastic behaviour after performing tensile relaxation tests.
