Squeezing flow of compressible viscoelastic material with partial slip

Original language description

This contribution deals with the problem of squeezing flow of compressible viscoelastic material considering partial slip at the surface of compressing circular plates. Rheological behavior of compressed samples is described by a power law model of shear deformation (consistency K and flow behavior index m) and viscoelastic properties are expressed using power law relation for first normal stress difference (K’, m’). Alternative formulation takes into account only elongation and normal stresses. Squeezed material is considered as a foam, i.e. incompressible continuous phase filled by air bubbles. Partial slip at wall is expressed by dimensionless parameter δ proportional to slip velocity that is independent of consistency and stresses. Suggested mathematical models result to analytical expression for axial force as a function of compression rate and the thickness of gap. The models are applied for experiment with the sample of collagen compressed between two parallel disks of the texture analyzer instrument TA-XT2i.
