Mechanical anisotropy at the nanoscale in amorphous solids

Journal of Applied Physics, 2015
Amorphous solids are randomly disordered without any long-range periodic atomic arrangement and thus appear isotropic. Here, we show in metallic glasses that this view does not hold at small scales: Strong mechanical anisotropy emerges when the sample size decreases below about 15 nm as shown by the marked deviation in stress-strain relations as well ...

Microstructure, Texture and Mechanical Properties Anisotropy of Ni-16Cr and Ni-16Cr-16Mo Solid Solution Alloys in Hot Rolled and Annealed Condition

Materials Today: Proceedings, 2015
Abstract Present work describes microstructure-texture-mechanical property anisotropy correlation of Ni-16Cr and Ni-16Cr-16Mo alloys in hot rolled and annealed condition. The high and low SFE values associated with Ni-16Cr and Ni-16Cr-16Mo alloys result in partial recrystallization after recovery and presence of twins in recrystallized grains ...

Supervised Machine Learning and Physics Machine Learning approach for prediction of peak temperature distribution in Additive Friction Stir Deposition of Aluminium Alloy

PLoS ONE, 2023
Additive friction stir deposition (AFSD) is a novel solid-state additive manufacturing technique that circumvents issues of porosity, cracking, and properties anisotropy that plague traditional powder bed fusion and directed energy deposition approaches.

An ultrasonic method for measuring residual mechanical stresses in the rims of solid-rolled railroad wheels that considers the intrinsic anisotropy of the material

Russian Journal of Nondestructive Testing, 2013
The acoustic properties of the material of solid-rolled railroad wheel rims are investigated. The results of the assessment of the intrinsic anisotropy of the material are reported. An analytical expression for calculation of the residual mechanical stresses in a rim that considers the effect of the material’s intrinsic anisotropy is obtained. A method

3D Modeling of the Utah Forge Reservoir Stimulation with Proppant Transport and Deposition

Day 2 Tue, October 17, 2023, 2023
The paper presents 3D modeling and analysis of hydraulic stimulations conducted at the DOE Utah FORGE EGS site. We simulated the Stage-3 field stimulation along with proppant transport and deposition and examined the injection pressure history ...

Anisotropy in the mechanical properties of lamellar solids and its effect on wear and transfer

Wear, 1966
Abstract Experiments have been made to determine the degree of anisotropy in mechanical properties of lamellar solids, such as graphite, MoS2, mica, PbI2, etc. Radioactive measurements of the wear of copper sliding against compacts of lamellar solids, together with qualitative assessment of surface damage on other metals, show that many of the solids

Mechanics of Angioplasty: Wall, Balloon and Stent

Mechanics in Biology, 2000
Studying the solid mechanics of angioplasty provides essential insight in the mechanisms of angioplasty such as overstretching the disease-free tissue, plaque disruption or dissection, redistribution inside the wall and lipid extrusion etc.

Stress-strain state of stone cross vaults

Bulletin of Science and Research Center of Construction
Introduction. The calculation of stone vaults in historical buildings employs an approach in which vaults are treated as elements “assembled” from three-hinged, two-hinged, and hingeless arches, with the determination of forces being carried out ...
