Solid behavior of anisotropic rigid frictionless bead assemblies [PDF]

, 2008
We investigate the structure and mechanical behavior of assemblies of frictionless, nearly rigid equal-sized beads, in the quasistatic limit, by numerical simulation.

ANISOTROPIC MECHANICAL PROPERTIES AND HARDENING MECHANISMS IN ZRO2–Y2O3 SOLID SOLUTION CRYSTALS

Izvestiya Vysshikh Uchebnykh Zavedenii. Materialy Elektronnoi Tekhniki = Materials of Electronics Engineering, 2017
The anisotropy of the mechanical properties of crystalline ZrO2 – 2.8 mol.% Y2O3 solid solutions has been studied. The crystals have been grown by skull melting technique. The microhardness and fracture toughness for different crystallographic planes have been tested by indentation with different indenter diagonal orientations.

Macroscopic model with anisotropy based on micro-macro informations [PDF]

, 2014
Physical experiments can characterize the elastic response of granular materials in terms of macroscopic state-variables, namely volume (packing) fraction and stress, while the microstructure is not accessible and thus neglected.

Fluid flow at the interface between elastic solids with randomly rough surfaces [PDF]

, 2010
I study fluid flow at the interface between elastic solids with randomly rough surfaces. I use the contact mechanics model of Persson to take into account the elastic interaction between the solid walls and the Bruggeman effective medium theory to ...

The influence of anisotropic growth and geometry on the stress of solid tumors [PDF]

, 2017
Solid stresses can affect tumor patho-physiology in at least two ways: directly, by compressing cancer and stromal cells, and indirectly, by deforming blood and lymphatic vessels.

Approximation of the Generalized Lame Equations by the Strain Energy Functional [PDF]

International Journal of Mathematical, Engineering and Management Sciences
This paper considers a linear system of partial differential equations (PDEs) to describe the stress-strain state of a two-phase body under static load, such as water-saturated soil.

Estimating of mechanical stresses, plastic deformations and damage by means of acoustic anisotropy

PNRPU Mechanics Bulletin, 2020
Acoustic anisotropy is a consequence of anisotropy of the mechanical characteristics of a solid. In metals, it is associated with microstructural anisotropy of mechanical characteristics, internal mechanical stresses and strains, including residual ...

Anisotropic Organised Eddy Simulation for the prediction of non-equilibrium turbulent flows around bodies [PDF]

, 2008
The unsteady turbulent flow around bodies at high Reynolds number is predicted by an anisotropic eddy-viscosity model in the context of the Organised Eddy Simulation (OES).

Influence of Rotations on the Critical State of Soil Mechanics [PDF]

, 2010
The ability of grains to rotate can play a crucial role on the collective behavior of granular media. It has been observed in computer simulations that imposing a torque at the contacts modifies the force chains, making support chains less important.
