Unification of the Rheological Physics of Yield Stress Fluids.

Physical Review Letters, 2021
The physics above and below the yield stress is unified by a simple model for viscoplasticity that accounts for the nonlinear rheology of multiple yield stress fluids.

Machine learning-based design strategy for 3D printable bioink: elastic modulus and yield stress determine printability

Biofabrication, 2020
Although three-dimensional (3D) bioprinting technology is rapidly developing, the design strategies for biocompatible 3D-printable bioinks remain a challenge. In this study, we developed a machine learning-based method to design 3D-printable bioink using

Yield stress criteria to assess the buildability of 3D concrete printing

, 2020
3D concrete printing (3DCP) using the extrusion method is a commonly used additive manufacturing technique to construct the structures layer by layer without using formwork.

Yield stress and thixotropy control of 3D-printed calcium sulfoaluminate cement composites with metakaolin related to structural build-up

, 2020
The three-dimensional (3D) structural build-up with the precision has proposed new requirements related to yield stress and thixotropy in the 3D-printed cementitious materials.

Effect of yield stress development on the foam-stability of aerated geopolymer concrete

, 2020
This study investigates the instability of fresh geopolymer foam concrete (GFC) synthesised through the pre-foaming technique, particularly at ultra-low densities (430–460 kg/m3).

Yield Stress Fluids Slowly Yield to Analysis

Science, 2009
The behavior of a type of complex fluid (exemplified by mayonnaise and concrete) can depend on the sample's flow history.

Coiling of yield stress fluids

Physical Review E, 2011
We present an experimental investigation of the coiling of a filament of a yield stress fluid falling on a solid surface. We use two kinds of yield stress fluids, shaving foam and hair gel, and show that the coiling of the foam is similar to the coiling of an elastic rope.

Helical Locomotion in Yield Stress Fluids

Physical Review Letters, 2023
We report three stages for locomotion of a helical swimmer in yield stress fluids. In the first stage, the swimmer must overcome the material's yield strain to generate rotational motion. However, exceeding the first threshold is not sufficient for locomotion.
