|Title:||Oscillatory torsional flow of a viscoelastic solid|
|Citation:||Phan-Thien, N. (2002-08). Oscillatory torsional flow of a viscoelastic solid. Computational Mechanics 29 (2) : 143-150. ScholarBank@NUS Repository. https://doi.org/10.1007/s00466-002-0325-z|
|Abstract:||We show that a voscoelastic solid, modelled by a three-dimensional analogue of the Kelvin-Meyer-Voigt equation (the neo-Hookean rubber-like body and the Oldroyd-B element in parallel), has an exact similarity solution in the torsional flow geometry, including inertia. Numerical results obtained by a finite difference method for the oscillatory torsional flow indicate that the flow loses its stability at high amplitudes of oscillations. This is partly explained by a linear stability analysis of a simpler flow generated by a constant angular displacement.|
