Quantifying Shear Thickening Behaviour Using the Power Law Model on a Rotational Rheometer
7 July 2015

This application note demonstrates how thickening behavior can be modeled using the power-law model. While most suspensions and polymer structured materials are shear thinning, some materials can also show shear thickening behavior where viscosity increases with increasing shear rate or shear stress. This phenomenon is also often referred to as dilatancy, and although this refers to a specific mechanism for shear thickening the terms are often used interchangeably.
