WebJun 28, 2016 · 3.2 Test Procedure. A rheometer was used to measure the rheological properties. In addition to the steady shear measurements, the rheometer is also capable of continuous strain sweep (i.e., at a constant frequency of oscillation the amplitude of the displacement is continuously varied) and frequency sweep (i.e., at a constant stress or … WebRheology. Rheology deals with time-dependent material deformation and flow under stress. Rheological testing investigates the elastic, viscous and viscoelastic behavior and properties of materials, under various shear and temperature conditions. Rheology tests can be done for a range of materials including liquids, semi-solids, gels, emulsions ...
