Materials with memory: some new results in viscoelastic models

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