Rheological Formulation Research Articles

Another word on the rheology of silicone putty: Bingham

Silicone putty, a material commonly used as a rock-analog in tectonic scale-model studies, exhibits rheological behavior that is similar to the Bingham rheological model over a wide range of strain rate. Nevertheless, at low strain rates a power law is a useful approximation. Similarly, at high strain rates a linear viscous model can be applied. Thus, the choice of rheologic expression can be based on knowledge of the range of stress levels that are achieved in a given model. Conversely, models can be designed to develop appropriate stress levels so that the rheological formulation appropriate to the relevant prototype material will be applicable.
