The modified temperature term on Johnson-Cook constitutive model of AZ31 magnesium alloy with {0002} texture

Journal of Magnesium and Alloys, 2020
The dynamic compression experiments with Split-Hopkinson Pressure Bar(SHPB) were performed on AZ31 magnesium alloy rolled sheet specimens in the normal direction (AZ31-ND) with {0002} texture at the temperature of 293–523 K and the strain rate of 0.001 ...

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

Nocturnal Intraocular Pressure Monitoring With a Soft Contact Lens Sensor for Glaucoma Management

Advanced Materials, EarlyView.
A soft contact lens sensor enables continuous, noninvasive monitoring of nocturnal intraocular pressure (IOP) under closed‐eye sleep conditions. By integrating a highly compliant inductive–capacitive circuit onto a commercial lens, the device achieves record sensitivity and stable performance.

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels

Advanced Materials Interfaces, EarlyView.
When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

FEM simulation for orthogonal cutting of Titanium-alloy considering ductile fracture to Johnson-Cook model

Mechanical Engineering Journal, 2016
FEM simulation for the orthogonal cutting of Ti-6Al-4V alloy was investigated. Johnson-Cook's model was used for a flow stress equation of material. Rigid-plastic analysis was carried out using DEFORM-2D and AdvantEdge which were commercial software.
