Abstract: Hydrated soft tissues such as articular cartilage can be considered as porous materials consisting of an organic solid matrix saturated by a pore‐fluid. These types of biological tissues exhibit significant viscoelastic behaviour because of flow‐dependent fluid‐solid interaction and flow‐independent viscoelastic skeleton properties. To describe this complex behaviour, a linear viscoelastic two‐phase model based on the macroscopic Theory of Porous Media is presented. The required linear viscoelastic constitutive law is given in differential form deduced from rheological considerations. Numerical examples within the finite element method show the applicability of the presented model. Furthermore, they reveal the influence of the flow‐independent viscoelasticity of the solid skeleton on the general behaviour of hydrated soft tissues, for example on articular cartilage.
