Recognition of the Stress-Strain Curve Based on the Local Deformation Measurement of Soil Specimens in the Triaxial Test

, 2016
A digital image technique was developed and used to measure the deformation distribution over the entire surface of soil specimens in triaxial tests. The measured deformation process shows that the specimen apparently exhibits three states during the ...

A study of the shear behavior of a Portland cement grout with the triaxial test

Construction and Building Materials, 2018
Abstract Numerous research has been conducted on the axial performance of cement-based grouts. However, much less work has been focused on the shear behavior of cement-based grouts. In this study, the shear behavior of a Portland cement grout was investigated with the triaxial test. Cylindrical samples with two different water-to-cement (w/c) ratios:

Shear Band Formation in Triaxial and Plane Strain Tests

1988
This paper presents the results of a combined theoretical and laboratory study of the formation of shear bands in triaxial compression, triaxial extension, and plane strain compression. The principal finding is that shear bands are initiated more easily under plane strain than under axially symmetric conditions of the triaxial test.

Strength of various sands in triaxial and cyclic direct shear tests

Engineering Geology, 2013
Abstract This paper presents the result of an extensive series of experimental investigation carried out in triaxial and cyclic direct shear tests on sands having various properties, which were obtained from different locations in Turkey and in Northern Cyprus. In order to investigate the link between strength and physical properties (i.e., shape) of

Continuous Monitoring of Bender Element Shear Wave Velocities During Triaxial Testing

, 2014
Bender element testing is used to measure shear wave velocities (VS) across soil specimens in the laboratory. Conventional bender element testing is carried out at a few discrete points during an experiment. This paper presents a method which uses bender

Energy Components During the Triaxial Cell and Direct Shear Tests

Géotechnique, 1964
Synopsis The components of energy loss during a triaxial cell test are examined critically. It is shown that the stress dilatancy equation may be derived by inserting a modified cell pressure into the Bishop energy correction. The physical reason for this is discussed and the correct solution is derived in three different ways.

Shear Strength and Shear-Induced Volume Change Behavior of Unsaturated Soils from a Triaxial Test Program

, 2008
A series of unsaturated soil triaxial tests were performed on four soils including sand, silt, and a low plasticity clay. Attempts were made to correlate unsaturated soil properties from these tests and data from the literature with soil-water ...

Shear Band Formation and Strength of Loess in True Triaxial Tests

Journal of Testing and Evaluation, 2019
Abstract This study presents experimental results from a strength test of loess from China’s Xi’an Bailu plateau. The measurements were made with a true triaxial apparatus. Some explored characteristics were shear stress ratio, intermediate principal strain and volumetric strain changing with major principal strain, and strength criteria
