Webenced operator to rapidly generate master curves and evaluate alternative theoretical models. Furthermore, TTS is fully supported in Rheology Navigator to allow completely unattended experimental evaluation and master curve generation once the sample has been loaded. Figures 1-5 show the steps involved in a typical application of the TTS … WebIn rheology, the force is expressed as shear stress (unit is pressure, Pascal) and the speed is expressed as shear rate (unit is reciprocal seconds, /s). A plot of shear stress versus shear rate is called a “flow …
