抄録

The most typical characteristic of the present model is that it consists of eight standard models with Langevin springs and a dashpot obeying strain-rate-dependent response. The computational simulations employing the constitutive equations clarify the mechanisms of hysteresis loss and the strain-rate-dependent nature of the response of rubber. We employed the homogenization method and proposed constitutive equation to correlate the micro- to macroscopic deformation behavior of Carbon-Black filled rubber. Representative computationally predicted and experimental results are compared to evaluate the adequacy of the present simulation.
