Identification Of Viscoelastic Model Of Filled Rubber And Numerical Simulation Of Its Time Dependent Response

  • Bohdana Marvalova
Part of the Springer Proceedings in Physics book series (SPPHY, volume 126)

The rate-dependent behavior of filled rubber was investigated in compression regimes. The viscosity-induced rate-dependent effects are described. The parameters of a constitutive model of finite strain viscoelasticity were determined by nonlinear optimization methods. The material model was implemented into finite element code and the viscoelastic stress response of carbon black filled rubber at large strains in relaxation, creep and cyclic loading was simulated.
