Experimental study of anisotropy and non-coaxiality of granular solids [PDF]

Granular Matter, 2015
Previous experimental studies of anisotropy and non-coaxiality by using the hollow cylindrical apparatus are mainly focused on granular soils, which feature irregular particle shapes and non-uniform particle size distributions. This paper experimentally investigates these two characteristics on assemblages of particulate materials with regular particle

Modelling of Non-coaxial Viscoplastic Deformation in Geodynamics [PDF]

Journal of Civil Engineering and Architecture, 2014
The formation of shear bands for time and length scales appropriate for deformation processes in the upper Lithosphere is investigated in plane strain finite element simulations under predominantly uniaxial extension and compression, respectively. The direction of gravity is assumed orthogonal to the extension/compression axis.

Non-coaxial plasticity of similar weakly cemented soft rock under directional shear stress path [PDF]

Scientific Reports
The plastic flow behavior of soft rock exhibits non-coaxial features under complex stress paths, while traditional plasticity theories are ill-equipped to adequately represent this, which leads to the mechanism of soft rock failure still unclear.

Micromechanical modeling of hollow cylinder torsional shear test on sand using discrete element method [PDF]

Journal of Rock Mechanics and Geotechnical Engineering
Previous studies on the hollow cylinder torsional shear test (HCTST) have mainly focused on the macroscopic behavior, while the micromechanical responses in soil specimens with shaped particles have rarely been investigated.

Accurate Computation of Mutual Inductance of Non Coaxial Pancake Coils [PDF]

Energies, 2021
The computation of self and mutual inductances of coils is a classic problem of electrical engineering. The accurate modeling of coupled coils has received renewed interest with the spread of wireless power transfer systems. This problem has been quite well addressed for coplanar or perfectly coaxial coils but it is known that the misalignment ...

A laboratory study of anisotropic geomaterials incorporating recent micromechanical understanding [PDF]

, 2016
This paper presents an experimental investigation revisiting the anisotropic stress–strain–strength behaviour of geomaterials in drained monotonic shear using hollow cylinder apparatus. The test programme has been designed to cover the effect of material

Spherical metrics with conical singularities on a 2-sphere: angle constraints [PDF]

, 2015
In this article, we give a criterion for the existence of a metric of curvature 1 on a 2-sphere with n conical singularities of prescribed angles 2πθ1,...,2πθn and non-coaxial holonomy.

Non-Axisymmetric Effects on Long Liquid Bridges [PDF]

, 1987
The stability of long liquid bridges under non-axisymmetric disturbances like a microgravitational force acting perpendicular to the liquid bridge axis or a non-coaxiality of the disks is analyzed through an asymptotic method based on bifurcation ...

Discrete element modelling of material non-coaxiality in simple shear flows [PDF]

, 2014
We investigate the quasi-static simple shear flow of a two-dimensional assembly of cohesionless particles using discrete element method (DEM) simulations.
