Application of Generalized Models for Identification of Viscoelastic Behaviour on Hysteretic Double Peak Materials

his paper investigates the capability of the fraction derivative Maxwell model to reproduce the mechanical behaviour of advanced viscoelastic materials, that are designed to be able to dissipate energy in an extended range of frequency than traditional viscoelastic materials and present a more complex shape of strain-stress frequency response. Fraction derivative models, compared to traditionally used generalized Maxwell model, can reproduce the material behaviour with a smaller number of parameters, reducing the utilization complexity and the computational burden
