High fidelity, discrete element method simulation of magnetorheological fluids using accurate particle size distributions in LIGGGHTS extended with mutual dipole method

Materials Research Express, 2021
We simulate magnetorheological fluids (MRF) using open source LIGGGHTS soft sphere discrete element method code, extended by us to include a mutual dipole magnetic model.

Field responsive mechanical metamaterials. [PDF]

, 2018
Typically, mechanical metamaterial properties are programmed and set when the architecture is designed and constructed, and do not change in response to shifting environmental conditions or application requirements.

Generality of shear thickening in suspensions [PDF]

, 2010
Suspensions are of wide interest and form the basis for many smart fluids. For most suspensions, the viscosity decreases with increasing shear rate, i.e. they shear thin. Few are reported to do the opposite, i.e.

Investigating the Benefit of MR fluids in Shock Absorbers [PDF]

, 2013
The beneficial properties of magnetorheological (MR) fluids are applied in the design and testing of a prototype suspension system. Because MR fluids become more viscous under the influence of a magnetic field, a suspension shock absorber containing MR ...

Analysis of the Composite Transmission of Magnetorheological Fluids and Shape Memory Alloy

Jixie chuandong, 2015
The magnetorheological effect of magnetorheological fluid reduce under a high temperature condition,which causes so many problems like the uncontrollability of the variation of shearing stress,and even failure of the transmission device.Based on the ...

Phase‐Change Alloys Enable Localized Reversible Stiffening and Actuation in Steerable Eversion Tip‐Growing Robots

Advanced Intelligent Systems, EarlyView.
This work presents a tip‐growing eversion robot that uses phase‐changing alloys for reversible stiffening and localized actuation, achieving 43× stiffness modulation, 15× force amplification, and segmental steering. The system enables precise navigation and force delivery in constrained, tortuous pathways.
