## What is Rheology Lite?

An App for Rheological analysis of the flow behavior of non-Newtonian materials. Determine the zero-shear-viscosity, shear-thinning-index, relaxation time, yield stress, flow activation energy, and WLF parameters.

Viscosity Models: Cross model, Carreau model, Carreau-Yasuda model.
Determine Zero Shear Viscosity, Relaxation Time and Shear Thinnning Index using these viscosity models.

Flow Curve Models: Power Law model, Bingham model, Herschel-Bulkley model, Casson model.
Determine Yield Stress, Bingham Plastic Viscosity, Consistency and Casson Viscosity using these flow curve models.

Temperature Models: Arrhenius model, WLF model.
Determine the Temperature Dependence of Viscosity, Flow Activation Energy and the WLF Constants using these temperature models.
