Non-coaxiality of sand under bi-directional shear loading [PDF]
This study aims to investigate the effect of consolidation shear stress magnitude on the shear behaviour and non-coaxiality of soils. In previous drained bi-directional simple shear test on Leighton Buzzard sand, it is showed that the level of non ...

Semi-implicit integration algorithm for non-coaxial model based on vertex theory and its application
A semi-implicit integration algorithm is presented for the non-coaxial model based on the yield vertex theory. In the stress updating considering the non-coaxial terms, the plastic flow direction is expressed explicitly.

Non-coaxial sand model based on improved vertex theory and its application
Although the non-coaxial models based on the traditional vertex theory can capture the non-coaxial behavior of sand, they contain some theoretical defects.

Discrete Element Simple Shear Test Considering Particle Shape
The particle shape has significant effects on the slip and rotation of particles in the shear of geomaterials, which is an important factor in the deformation and strength of geomaterials.

Due to the coaxial assumption that the direction of plastic strain rate is the same as that of stress, the non-coaxial behavior of sand under non-proportional loading conditions can not be captured by the conventional elastic-plastic model. In this study,

Effects of non-coaxiality and soil anisotropy on tunneling-induced subsurface settlements
Nowadays, constitutive models for soils used for numerical modelling of tunnelling are normally restricted to the assumption of soil strength isotropy and coaxiality.

A correctly designed machine is characteristic of low vibration values. However wear processes occur during its operation. They are accompanied by a lack of balance of its rotating parts and elements, which results in non-coaxiality of shafts.
