A new approach to measuring both the steady flow curve and the planar extensional viscosity of complex fluids using exponential shear
Nicholas King, Eugene Pashkovski, Reid Patterson +1
We revisit the protocol known as Exponential Shear (ES), first proposed by Doshi and Dealy in 1986. This is a transient strong flow that can be readily imposed in the laboratory us…

Self-Consistent Fourier-Tschebyshev Representations of the First Normal Stress Difference in Large Amplitude Oscillatory Shear
Nicholas King, Eugene Pashkovski, Reid Patterson +2
Large Amplitude Oscillatory Shear (LAOS) is a key technique for characterizing nonlinear viscoelasticity in a wide range of materials. Most research to date has focused on the shea…
