Rheology and rheometry of highly filled reactive materials

The modeling and experimental investigation of the flow of highly filled reactive materials is studied. For significant numerical simulations it is of decisive importance that the material considered is characterized for all constitutive equations, although experimental problems still exists. The most important constitutive equation is the rheological equation for the stress tensor. For highly filled reactive materials, the usual characterization techniques fail. A new characterization method is proposed which circumvents these problems. In this method complex flows are encountred and differences between numerical and experimental results are used to adjust the parameter values and/or the constitutive model.
