Parameter Identification of Fractional Index Viscoelastic Model for Vegetable-Fiber Reinforced Composite

In the present work, parameters for adapting the behavior of the uniaxial three-element viscoelastic constitutive model with integer and fractional index derivatives to the mechanical evolution of an epoxy-composite material reinforced with long random henequen fibers, were determined. Cyclic loadin...
