## Abstract A model based on the concept of fractional calculus is proposed for the description of the dynamic elastic modulus, __E__\* = __E__β€² + __iE__β€³, of polymer materials. This model takes into account three relaxation phenomena (Ξ±, Ξ², and Ξ³) under isochronal conditions. The differential equa
