Abstract [en]

Torsional wave amplitude for tough, rubber like, doubly crosslinked hydrogel decreases rapidly with propagation distance where maximum decrease after one wave length is at frequency with maximum loss factor of shear modulus. Doubly crosslinked hydrogel is containing macromolecular polymer network with both chemical and physical crosslinks where it is possible to adaptively tune the frequency for maximum loss factor of shear modulus. This rubber like material has thus a potential to serve as vibration isolator and damper. Torsional dynamic stiffness of a cylindrical vibration isolator is modelled, displaying resonances and anti-resonances with a strong damping.
