Improved Maxwell Model Approach and its Applicability toward Lifetime Prediction of Biobased Viscoelastic Fibers

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