Numerical Analysis of non Linear Thermosensible Viscoelastic Systems
In this paper will be present a numerical approach to the dynamic analysis of rubber-to-metal devices. These objects, which contain viscoelstic materials, work in extreme conditions by the point of view of vibrations and thermical shocks and their behaviour can hardly be defined in an analytical way, because of their strong non linearity properties, thermosensibility and viscoelasticity.
Analysis is performed in three stages: first is an experimental characterization of material dynamic behaviour; second is material model parameters estimation; third stage is numerical analysis of complex system model involved by an automatic calculus code. The results of this process have been successfully compared with those taken from the experimentation.
