Ehlers, Wolfgang; Markert, Bernd Intrinsic viscoelasticity of porous materials. (English) Zbl 0986.74025 Sändig, A.-M. (ed.) et al., Multifield problems. State of the art. Berlin: Springer. 143-150 (2000). The authors present a two-phase model accounting for both flow-dependent fluid-solid interactions and intrinsic skeleton viscoelasticity. In particular, the authors demonstrate that the description of dissipative phenomena of porous solid skeleton requires a viscoelastic material formulation including the property of structural hardening towards the point of compaction. The paper ends with two numerical examples – a torsion test and a hydrostatic compression test – where the viscoelastic two-phase model is implemented into PANDAS, an adaptive finite element code for multi-phase problems.For the entire collection see [Zbl 0958.00018].
