The Hypoplastic Constitutive Model for Sandy Soil Considering the Rotation of the Principal Stress Axis

open access: yesApplied Sciences, 2023
Considering the influence of fabric on the critical state of sandy soil, an anisotropic hypoplastic constitutive model is developed by introducing the anisotropic critical state line that takes into account the rotation of the principal stress axes. With

Principal stress rotation as cause of cyclic mobility [PDF]

open access: yesGeotechnical Research, 2015
Principal stress rotation (PSR) has been known to act as ‘loading’ on soils since the seminal work of Arthur et al. some 30 years ago, using the directional shear cell. However, the key insight – reflected in the titles of the original papers – that soils yield under constant stress invariants if the principal stresses rotate, has been consistently ...

Ground Response and Mining-Induced Stress in Longwall Panel of a Kilometer-Deep Coal Mine

open access: yesShock and Vibration, 2021
In order to improve ground control of the longwall mining, ground response and mining-induced stress in the longwall panel of a kilometer-deep coal mine are investigated in this study.

Influence of principal stress direction on the stress-strain-strength behaviour of completely decomposed granite [PDF]

open access: yesFacta Universitatis. Series: Architecture and Civil Engineering, 2010
The measurement and study of the stress-strain-strength behavior of soils in general stress states involving principal stress rotation are necessary and valuable. To investigate the strength behavior under principal stress rotation, a series of undrained

Experimental study on strain accumulation characteristics of saturated remolded loess under pure rotation of the principal stress axis

open access: yesFrontiers in Ecology and Evolution, 2023
The study conducted a pure rotation test of 720° for saturated remolded Q2 loess under principal stress axis (PSA) rotation when deviatoric stress and the intermediate principal stress ratio are different, also paying attention to examining the changes ...

Incremental response of granular materials: DEM results [PDF]

open access: yes, 2009
We systematically investigate the incremental response of various equilibrium states of dense 2D model granular materials, along the biaxial compression path (\sigma 11 < \sigma 22, \sigma 12 = 0). Stress increments are applied in arbitrary directions in

Characteristics of cumulative plastic strain and critical dynamic stress of frozen clay under principal stress rotation

open access: yesYantu gongcheng xuebao, 2023
As the foundation of cold region projects and the supporting wall of artificial freezing projects, the frozen soil often bears the disturbance of dynamic loads.

A note on Skempton's A parameter with rotation of principal stresses

open access: yesGéotechnique, 1978
This Paper proposes a system of defining the major and minor principal stress increments in the Skempton's (1954) pore pressure equation. Using this system, a unified trend emerges for use in analysing published data that are seemingly conflicting. The system is also shown to give a consistent interpretation, both theoretically and experimentally, to ...

Deformation behavior of K0-consolidated soft clay under traffic load-induced stress paths

open access: yesYantu gongcheng xuebao, 2017
Under traffic loads, the magnitudes and directions of the principal stresses applied in the soil elements of soft subgrade change simultaneously. Namely, as the shear stress changes in amplitudes, the principal stress axes continuously rotate.
