Fault activity is a factor causing geological disasters and controlling their spatial distribution. The information on fault activity can be recorded by the microstructure of the fault gouge sliding surface, which provides an approach to study the ...

Effect of Testing Procedure in Ring Shear Tests
Geotechnical Testing Journal, 1988Abstract This technical note describes a comparison between the results obtained from single-stage and multistage ring shear tests on two different types of normally consolidated clay. The results confirm the brittle behavior of normally consolidated soils containing a high proportion of clay particles and the curved nature of the ...

Evolution of Shear-Zone Structure in Undrained Ring-Shear Tests
Landslides, 2004Undrained monotonic torque-controlled tests were conducted on fine-grained silica sand to study the shear-deformation process in granular materials by using a ring-shear apparatus. Shear-zone structures at various stages in the undrained shear tests were observed during a series of tests in which the experiments were terminated at different shear ...

"Ester"-A new ring-shear-apparatus for hydrate-bearing sediments.
Review of Scientific Instruments, 2020We developed a new thermostated ring-shear-apparatus for investigation on hydrate- or ice-bearing sediments. A fluid inlet at the bottom of the static part of the cell and a fluid outlet at the top of the rotating half-cell allow exchanging and ...

Drained Shear Displacement Rates in Fully Softened Strength Torsional Ring Shear Testing
Geotechnical Testing Journal, 2020To measure the fully softened strength, the normally consolidated and reconstituted specimen must be drained, i.e., no development of shear-induced pore-water pressures, during shearing.

Ring Shear Testing of Deposited Coatings
1987This paper discusses ring shear tests for quantitatively measuring the adhesion between metal coatings and their substrates. Details are presented on the testing procedure and the various substrate-coating combinations that have been evaluated by this method.

Rapid estimation of residual shear strength by ring shear test
2011The residual shear strength of the soils is one of the main inputs for analyzing the stability of pre-failed slopes and the progressive failure problems, which generally occur in fissured clay slopes, caused by strength reduction with displacement. In practice, it is important to decide the residual shear strength parameters as quick as possible in an ...
