Stress Path Tests with Controlled Rotation of Principal Stress Directions

1981
University College London (UCL) has developed a new flexible boundary plane strain shear apparatus for investigating stress-strain-strength anisotropy in sands. Called the Directional Shear Cell (DSC), it has the unique capability of controlling the major principal stress direction by varying the normal stress and shear stress acting on four faces of a

Rotating Principal Stress Axes in High-Cycle Fatigue

Journal of Basic Engineering, 1967
A new modified octahedral shear stress failure theory for high-cycle fatigue has been developed. This theory considers rotating principal stress axes and nonsynchronous stresses. This theory was then compared to the commonly used octahedral shear stress theory using data from the literature.

A Theory in Finite Differences for Computation of Interchanging Principal Stresses and Principal Axes Rotation

Journal of Applied Mechanics, 2013
Suppose consecutive ordinates of three arbitrary and nonproportional stress-time functions of plane state of stress are entered into a computer by a little finite time step. The theory proposed solves the following problem: correct computation of the ordinates of the principal stress-time functions and the angle of principal axes rotation. This problem

Considerations on soil response to the rotation of principal stress directions

Computers and Geotechnics, 1989
Abstract The paper evaluates various plasticity formulations in the context of their ability to describe the influence of the rotation of principal stress axes. The discussion extends to a new theoretical framework which incorporates an implicit measure of material microstructure, derived from the directional distribution of porosity.

Effects of Cyclic Rotation of Principal Stress Axes and Intermediate Principal Stress Parameter on the Deformation Behavior of Sands

Geotechnical Earthquake Engineering and Soil Dynamics IV, 2008
Four series of drained tests on sands were performed with a hollow cylinder apparatus in order to investigate the fundamental deformation behavior of sands and the effects of the intermediate principal stress parameter b during cyclic rotation of principal stress axes.

Elastico-Plastic Straining when the Principal Stresses Rotate

Nature, 1950
IN recent years there has arisen a controversy, on theoretical grounds1, on whether post-yield straining of metals should be analysed by considering : (I) plastic increment-strain components only (Levy, about 1870, and Mises later2); (II) plastic total-strain components only attained instantaneously (Nadai, 1931 3) ; (III) plastic + elastic increment ...

Behaviour of sand under simultaneous increase in stress ratio and rotation of principal stresses

2011
Drained behaviour of sands under simultaneous increase in stress ratio and principal stress rotation is investigated. The hollow cylinder torsional (HCT) device which permits independent control of four stress parameters: mean normal stress σ'[subscript]m, stress ratio R, intermediate principal stress parameter b and the inclination α[subscript]σ of σ ...
