Abstract Published creep equations, derived from the Kelvin-Voigt model with a discrete retardation time spectrum were used to generate data for linear presentation of the creep function. It is shown that 2–3 term creep functions, containing 4–6 constants, could be reduced to an algebraic expression having two constants only. Consequently, entire creep curves of a variety of biological and food materials could be described by a single type of equation in the form of:P (t) = k 0 + k1 t + t/(k2 + k3t) whereP (t) is the creep parameter (compliance, strain or deformation),k 0 a constant representing the instantaneous compliance,k 1 a constant representing the steady-state flow, andk 2 andk 3 the characteristic constants of the creep functionψ (t) obtained by regression from the linear relationship oft/ψ (t) vst.
