MODELING OF NON-ELASTIC DEFORMATION RESPONSE OF RUBBER NANOCOMPOSITES
Original language description
This paper describes modeling of dynamic mechanical properties of heterogenous rubbery material with nanometer size inclusions. Model of calculation loading-unloading tensile curves heterogenous rubbery network was presented. The material was considereda tetrafunctional network of amorphous chains with solid inclusions. The chains in the vicinity of the inclusion were considered immobilized. The dynamic response was modeled as a time dependent of chains slippage in the entanglement. The model was tested by virtual loading-unlading experiment. The sample was deformed with defined deformation rate until double elongation and released back to the zero-stress. Numerical value of dissipated energy density was calculated as a surface delimited by tensile deformation and unloading curves. Heterogenous network showed non-elastic or nonlinearly elastic response. The tensile deformation curves and unloading curves were not aligned and dissipation of the energy during the loading unloading cycle
