Characterization of time- and/or frequency-dependent material properties usually requires shifting of the measured segments according to the Time-Temperature Superposition principle. This paper presents a closed form mathematical methodology (CFS) which completely removes ambiguity related to the manual shifting procedures. The derivation of the shifting algorithm is presented, and its validation using several simulated- and real- experimental data. It has been shown that error caused by shifting performed with CFS is at least 10–50 times smaller then the underlying experimental error.

This paper presents the analysis of time-dependent behaviour of polymeric (viscoelastic) materials under cyclic loading conditions that polymeric products, such as transmission belts, are exposed to during their operation. Time-dependent behaviour of cyclically loaded transmission belts is studied through the newly developed methodology for analyzing strain accumulation process that may be one of the mechanisms responsible for the hardening of material, crack formation, and ultimately for the failure of polymeric products.
