Abstract
The classical model of viscoelastic body is reconsidered. As well known thedeformation response of a material is termed viscoelastic when it does not depend only on the statusof the material in the considered time, but also on its deformation history. Furthermore, the systemis dissipative: such dissipative nature induce the use of viscoelastic materials in devising anti-seismic dissipators. Aiming to model new and innovative materials different forms of therelaxation modulus which characterises the response of the material are considered. Cases of a non-classical relaxation modulus are studied. Thus, a relaxation modulus which may be unbounded orless regular or modified to describe a material whose mechanical response is changed when thematerial with time, this phenomenon is usually termed ”aging” are investigated. Finally, theviscoelastic response can be controlled on devising magneto-viscoelastic materials via injection of micro or nano particles magnetically sensible.File | Dimensione | Formato | |
