Statistical Description of Triaxial Shear Test Results
Geotechnical Testing Journal, 1990Abstract Any probabilistic approach to slope stability assessment requires an adequate statistical description of soil strength. Current statistical methods of strength description are unsuitable for this purpose. A statistical technique of soil strength description appropriate for the probabilistic assessment of slope stability in c′, φ′

Triaxial shear testing of polished slickensided surfaces
Landslides, 2011A series of consolidated-drained triaxial tests were performed on precut and polished clay specimens to measure their drained residual strength. Two soils were tested during this research program: Rancho Solano Clay and San Francisco Bay Mud. Specimens were tested using a specially modified triaxial compression device which was developed to minimize ...

Triaxial Shear Tests on Pervious Gravelly Soils
Journal of the Soil Mechanics and Foundations Division, 1956Tests to determine shear characteristics of free draining gravelly soils; relations between shear resistance and density, amount of gravel, gradation, maximum particle size, and particle shape; effect of testing speed on shear test data and effect of specimen size for any maximum particle size up to 3 in.

A Triaxial-Measurement Shear-Test Device for Soft Biological Tissues
Journal of Biomechanical Engineering, 2000A novel shear-test device for soft biological tissue, capable of applying simple shear deformations simultaneously in two orthogonal directions while measuring the resulting forces generated in three axes, is described. We validated the device using a synthetic gel, the properties of which were ascertained from independent tensile and rotational shear ...

On Comparing Simple Shear and Triaxial Test Results
Journal of Geotechnical Engineering, 1984It is indisputable that nonuniformities of stresses and strains exist in soils tested not only in the simple shear apparatus (SSA) but in the triaxial apparatus as well. These nonuniformities alone cannot explain the differences observed from the results of soils tests in the SSA and the triaxial apparatus.

Shear Stress and Pore Pressure in Triaxial Testing
Journal of the Soil Mechanics and Foundations Division, 1965The effects of frictional end restraint in triaxial testing may be avoided by using lubricated loading platens or segmental specimens. Segmental specimens consist of a central segment sandwiched between end segments that are sealed in a latex film. Pore pressures are measured only in the rather uniformly stressed central zone. Using this technique, the

Effects of Shear Band Formation in Triaxial Extension Tests
Geotechnical Testing Journal, 1996Abstract The stress-strain and strength behavior from conventional triaxial extension tests is usually erratic due to excessive influence of necking in the hardening regime followed by shear banding. Two techniques have been attempted to impede the onset and gross development of strain localization. These resulted in macroscopically more

Shear fracture energy of Stripa granite- results of controlled triaxial testing
Engineering Fracture Mechanics, 1990Abstract We have performed controlled triaxial experiments on Stripa granite in a ‘nearly stiff’ environment. This means that, before the commencement of loading, an initial confining pressure was ‘locked’ in the pressurizing chamber of the triaxial vessel.

Shear Banding in True Triaxial Tests and Its Effect on Failure in Sand
Journal of Engineering Mechanics, 2001The occurrence of failure, mechanisms that create failure, and soil behavior in the vicinity of failure have been investigated. One mechanism is smooth peak failure, in which the soil continues to behave as a continuum with uniform strains, and smooth peak failure is followed by strain softening.
