Dynamic Viscoelastic Modeling of Interfacial Debonding for Magnetorheological Nanocomposites (INVITED)

Abstract eng:
A dynamic viscoelastic interface model is proposed to study the effective magneto-mechanical responses of magnetorheological nanocomposites filled with carbon nanotubes. It is incorporated with the Eshelby’s micromechanics and the elastic-viscoelastic correspondence principles. The effective dynamic stiffness and damping of randomly-dispersed, chain-structured nanocomposites are investigated with the consideration of imperfect interfacial condition between the filler and matrix. Comparisons are performed between the model-based simulation and the experimental data for a specific type of multi-walled carbon nanotube reinforced elastomer nanocomposites to demonstrate the potential of the proposed framework.
