Bending test for capturing the fractional visco-elastic parameters: theoretical and experimental investigation on giant reeds

Abstract

In this paper attention is devoted on searching a proper model for characterizing the behavior of giant reeds. To aim at this, firstly, meticulous experimental tests have been performed in the Laboratory of structural materials of University of Palermo. Further, the novel aspect of this paper is that of using an advanced Euler-Bernoulli model to fit experimental data of bending tests. Such a model of continuum beam takes into account different constitutive laws of viscoelasticity, being real materials visco-elastic.
