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…

Stable and Interpretable Multi-Mode Rheological Universal Differential Equations (mmRUDEs) for Data-Driven Constitutive Modeling
Mohua Das, Nicholas King, Navid Azizan +1
The Rheological Universal Differential Equation (RUDE) framework embeds neural networks within a frame-indifferent tensorial constitutive backbone and so enables data-driven discov…

Kinematic and rheological equivalence of steady shearing and planar extensional flows
Nicholas King, Gareth H. McKinley
Steady shearing and planar extension are commonly viewed as two distinct types of flow field, especially in the context of probing the rheology of complex fluids. By leveraging the…
