- Аннотация: The evaluation of relaxation measurements is a well-established technique for predicting the lifetime of polymer materials, with research primarily focusing on increasing prediction accuracy and minimizing material testing time. The current study presents a novel approach toward describing the long-term behavior of viscoelastic polymers based on the Maxwell model. It assumes a mean relaxation time of the polymer chains in conjunction with a dimensionless number that accounts for averaged polymer chain inhomogeneities. This coefficient is analogous to the dimensionless number, which successfully describes the asymmetry of both the Weibull distribution and of particle size distribution according to the Rosin, Rammler, Sperling and Bennet model. In comparison to earlier models based on time-superposition principles, the current approach enables lifetime prediction using a single short-term measurement, which must be taken at a properly chosen applied strain. The applicability of the new model in predicting the long-term behavior has been demonstrated by the analysis of the relaxation behavior of semi-crystalline bio-based fibers.
