    Damping in rubber in Finite Element analysis

    Hi I have to model rubber in a direct time integration analysis in a wide frequency range (10 to 1000 Hz) where the internal material damping of the rubber at high frequencies should be modelled as well. I only have one tan (delta) value for the highest frequency. I would prefer to use the...

    rayleigh damping instead of visco-el material?

    Hi I have to model rubber in a direct time integration analysis where the internal material damping of the rubber at high frequencies should be modelled as well. I would prefer to use the Rayleigh damping to estimate these damping effects in the structure than setting up a visco-elastic...
