Notes:
Compressive creep curves of potato flesh and cheddar cheese were fitted by a modified, four parameter model of the kind J(t) = Ko+ K1t + t/(K2+K3t) where J(t) is the compliance and the K's characteristic constants. The curves were fitted both with and without correction for cross-sectional area expansion and the nonlinearity of the strain. The fit of the model was comparable to that of the discrete Kelvin-Voigt model with 4 or 6 constants. The magnitude of the modified model constants was indicative of the general rheological character of the material and the stress dependency of the nonlinear viscoelastic behavior.
