Linear Viscoelasticity Linear viscoelastic materials are those for which there is a linear relationship between stress and strain (at any given time), . As mentioned before, this requires also that the strains are small, so that the engineering strain measure can be used (since the exact strain is inherently non-linear).

Keywords: dynamic mechanical testing, viscoelasticity, Hookean body, Newtonian fluid, relaxation time, , VISCOELASTICITY Most materials are not purely viscous and often show significant elastic behavior. Such materials are referred to as viscoelastic materials and the key parameter, the time determines whether viscous or elastic behavior prevails.

The linear viscoelastic region of a material is determined in an oscillatory measurement at a constant frequency with increasing stress or strain amplitude. The measured Moduli remain constant as long as the critical strain has not been reached. The end of the linear region is given by a decrease in viscosity or elastic modulus and an increase of
