A strain-softening phenomenon was observed when the cyclic effective stress path reached the failure line determined by the monotonic test. The cyclic strength of clay subjected to multidirectional cyclic shear stresses (i.e., circular and elliptical stress paths) was 0.775ηtimes that under ...
shear stress is applied to the sample. The vertical and horizontal loads are applied pneumatically and are controlled seperately by two regulating valves.The base of the simple shear box is connected with the excitor which applies the cyclic shear stress to the sample. The amplitude and the ...

This is because shafts that, for example, are hollowed out and contain all of their mass in a cylindrical ring behave differently than solid shafts of the same diameter. For torsion on both hollow or solid shafts, a quantity called shear stress, represented by τ (the Greek ...
Boundary equilibrium (8a) allows to evaluate the shear stress at lower and upper limits of the cross-section –τ|hl and τ|hu respectively– that thereafter we interpolate through linear functions (Step 2). In order to satisfy Eq. (14c) we add a bubble function to the linear shear ...
The model retains the extreme versatility and accuracy of the simple multi-surface J2-theory in describing observed shear nonlinear hysteretic behaviour, shear stress-induced anisotropy; and reflects the strong dilatancy dependency on the effective stress ratio. The theory is applicable to general three...
Flow path: (1) magnetic stirrer with open reservoir; (2) peristaltic pump; (3) 3D printed channel with a conductive floor and ceiling in the test section. Full size image The system was first tested using KCl saline solutions to achieve mass concentrations of 0.5%, 1%, 2%, and 4% in ...

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. This paper employed particle flow code (PFC3D) to simulate the si
Toward the end of each steady shear stress—just before the flow was stopped—and a short time after the no flow condition prevailed, a set of images was taken for the statistical analysis. For all the experiments, the no-flow rest time appears to have a negligible effect on the drop ...
