On the passage to linearized viscoelasticity

Web27 de jan. de 2024 · This article concerns itself with modelling of the nonlinear response of a class of viscoelastic solids. In particular, nonlinear viscoelasticity of strain rate type, which can be described by a constitutive relation for the stress function depending not only on the strain but also on the strain rate, is considered. WebTo motivate our linearization approach for this implicit time-discretization problem, we rst con- sider the case of (already) linearized viscoelasticity. Here, we simply recover the original evolution equations, which (neglecting any forces) are given by the linear Kelvin-Voigt viscoelasticity problem div(Cru+ Dru_) = 0 in [0;T] ; u= u
