The shear-thinning behaviour of a liquid is represented in terms of a relaxation time$łambda$, defined by the ratio$\eta$0/G0 of initial viscous and elastic constants. The relationship provides a very simple basis for the evaluation of$łambda$ andG0 from viscosity/shear data. Results are compared with relaxation times and moduli from primary normal-stress measurement, from stress relaxation and from direct measurement of recoverable shear strain. Good agreement is found but there is experimental evidence the recoverable shear strain$\gamma$e is related to normal stressN1 and shear stress$\sigma$ by$\gamma$e = N1/3$\sigma$, which does not agree with the theoretical prediction of eitherWeissenberg orLodge.
