ABSTRACT
This one-dimensional material law has been further extended to include time-dependent effects and implemented into finite element code using a concept of representative directions, which would allow the generalization of one-dimensional model to compute three dimensional stress-strain states (Freund et al. 2011). The model shows very good agreement with the standard quasi-static multihysteresis tests on CB-filled NR. In addition to this, the dynamic response of the material was validated against the time-dependent experiments such as strain rate dependency, amplitude dependency and stress relaxation tests. The major advantage of the model is its physically meaningful parameters and the ability to reproduce the material response at different loading rates using the same parameter set for each rubber compound. The implementation into finite element code enables to simulate more complex geometries.
