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 ...
The ShearTrac II cyclic direct simple shear (CDSS) system performs the consolidation and cyclic shear phases of a test under fully automatic control. The DSS test generates a fairly homogeneous state of shear stress throughout the specimen, which provides initial stress condition, stress path, and...

It is shown that this element may be subjected to perfect simple shear using four different boundary condition types. Each boundary condition type results in the same effective stress path, but different total stress paths and excess pore pressures. The boundary condition types are related to DSS ...
1d). They reduced the gage section thickness from 1.55 to 0.7 mm using an 8 mm diameter ball end mill (with a milling path diameter of 36 mm). Traphöner et al. (2021) adopted a non-circular generatrix for the toroidal groove which guarantees (in theory) a constant shear stress ...
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 ...
To see why the background solution given by the model (105) is dual to some elastic medium, we look at the spin-2 perturbations h_{xy} which encodes the information about the Green's function of the stress tensor T_{xy} on the boundary. Interestingly, the shear equation is massive: ...
Experiments test the dependence of shearing stress on the first two gradients of shear strain. The tests were conducted by direct numerical simulation using the Discrete Element Method (DEM) on a large two-dimensional (2D) assembly of circular disks. The assembly was coerced into non-uniformly de...
Whereas, in some published fracture mechanics work, the terms “true mode II or true mode III fracture” refer to the conditions where the fracture propagation path is along the initial crack plane, similar to the mode I case. Some test specimens such as punch through shear (PTS) [154], ...
In the worldsheet theory the time delay is proportional to the energy of the colliding particles (in the relativistic limit) as a shear consequence of the black hole size (the same is true for the scattering on the worldsheet of fundamental strings [17]), while in the T = −1 s ...
