Kelvin body

[′kel·vən ‚bäd·ē]
(mechanics)
An ideal body whose shearing (tangential) stress is the sum of a term proportional to its deformation and a term proportional to the rate of change of its deformation with time. Also known as Voigt body.

The generalized Kelvin model is presented in Figure 1, consisting of a Kelvin body and a Hooke body in series.
[k.sub.1], [[eta].sub.1] , and [[epsilon].sub.1] are the elastic modulus, viscosity coefficient, and strain of the Kelvin body, respectively; [k.sub.2] and [[epsilon].sub.2] are the elastic modulus and dependent variable, respectively.
Viscoelastic properties are modeled by a generalized Kelvin body, extensively used to interpret viscoelasticity in biological materials (Fung, 1993).
