Since the first publications of large amplitude oscillatory shear (LAOS) responses of
polymeric materials in the 1960s, different approaches have been developed to express …

Materials that exhibit yielding behavior are used in many applications, from spreadable
foods and cosmetics to direct write three-dimensional printing inks and filled rubbers. Their …

In the last two decades, advances in synthetic, experimental and modeling/simulation
methodologies have considerably enhanced our understanding of colloidal suspension …

Large amplitude oscillatory shear (LAOS) is used as a tool to probe the nonlinear
rheological response of a model elasto-viscoplastic material (a Carbopol microgel). In …

Guided by a series of discriminating rheometric tests, we develop a new constitutive model
that can quantitatively predict the key rheological features of waxy crude oils. We first …

Nanocellulose is a sustainable nanomaterial and a versatile green platform that has
attracted increasing attention. Although the wide applications of its aqueous suspensions …

Single polymer dynamics offers a powerful approach to study molecular-level interactions
and dynamic microstructure in materials. Direct visualization of single polymer chains has …

A constitutive model for elasto-viscoplastic thixotropic materials is proposed. It consists of
two differential equations, one for the stress and the other for the structure parameter, a …

Rheological material functions are used to form our conceptual understanding of a material
response. For a nonlinear rheological response, the possible deformation protocols and …
