Generation of internal stress and its effects [PDF]
, 2010 Internal stresses may be generated continually in many polycrystalline materials. Their existence is manifested by changes in crystal defect concentration and arrangement, by surface observations, by macroscopic shape changes and particularly by ...

PREMISES OF IDENTIFYING EQUIPMENT FOR CUTTING BY ELECTROCHEMICAL MACHINING
Nonconventional Technologies Review, 2021 The study of residual stresses in metal parts can be performed by making slits where such stresses are assumed to exist. Measuring the width of the slits can provide information on the type and size of residual stresses.

Sheared active fluids: thickening, thinning and vanishing viscosity [PDF]
, 2010 We analyze the behavior of a suspension of active polar particles under shear. In the absence of external forces, orientationally ordered active particles are known to exhibit a transition to a state of non-uniform polarization and spontaneous flow. Such

Magnetic Properties and Applications of Glass-coated Ferromagnetic Microwires
Advanced Electromagnetics, 2023 A remarkable magnetic softness and giant magnetoimpedance (GMI) effect at GHz frequency range havebeen observed in glass-coated microwires subjected to appropriate postprocessing. Co-based microwires present higher GMI effect.

Micro-slurry jet for surface processing of dental ceramics
Biosurface and Biotribology, 2019 A micro-slurry jet (MSJ) was used for removing microscopic cracks and microstructural defects on surfaces of dental ceramics, in which the MSJ functioned as a wet blasting machine using mixed alumina particles and water to spray workpiece surfaces by a ...

High Strain-Rate Material Model Validation for Laser Peening Simulation
The Journal of Engineering, 2015 Finite element modeling can be a powerful tool for predicting residual stresses induced by laser peening; however the sign and magnitude of the stress predictions depend strongly on how the material model captures the high strain rate response.
