Triaxial tension–compression tests for multiaxial cyclic plasticity

International Journal of Plasticity, 1999
Abstract The aim of this paper is to present triaxial tension–compression tests and a new triaxial specimen devoted to the study of cyclic plasticity under non-proportional loadings. Because the stress state in the central part of the specimen is not homogeneous, the analysis of the tests need a 3D finite element computation.

Defining Y2 Yielding From Cyclic Triaxial Tests

Geotechnical Testing Journal, 2013
Abstract This paper presents the yielding characteristics of overconsolidated Bootlegger Cove Formation (BCF) clays extracted from the Port of Anchorage construction site. Additionally, it extends the critical shear strain concept to define the point at which irrecoverable deformations begin (Y2 yielding) to the case of fully reversed ...

Static and Cyclic Triaxial Testing of Ballast and Subballast

Journal of Geotechnical and Geoenvironmental Engineering, 2005
This paper discusses the triaxial testing of a ballast material and a subballast material, which are noncohesive, granular materials pically used for construction of a railway track substructure. Both static and cyclic triaxial tests were conducted. The cyclic triaxial tests simulated the behavior of these railway substructure materials under a large ...

A Compilation of Cyclic Triaxial Liquefaction Test Data

Geotechnical Testing Journal, 1979
Abstract A data base on cyclical soil strength would be of significant assistance in many phases of site evaluation where detailed complete cyclical soil testing is not available or could not economically be obtained. The objective of this study was to develop a partial data base for determining the seismic strength of saturated ...

Cyclic triaxial tests with continuous measurement of dissipated energy

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1983
Abstract This article describes conventional cyclic triaxial tests on a uniform sand in which the amount of energy dissipated by the specimen was continuously monitored. Energy monitoring was achieved by means of a digital circuit that automatically integrated the force-displacement signals as the test progressed.

Cyclic loading triaxial testing of crushed rubble and lava

Bulletin of the International Association of Engineering Geology, 1984
This paper describes a laboratory investigation into the suitability of crushed rubble as a substitute for conventional road base materials. The rubble investigated was a mixture of crushed concrete and crushed bricks, whilst lava from the Eifel was chosen as a reference material.

The stable state in cyclic triaxial testing on sand

Soil Dynamics and Earthquake Engineering, 1994
Abstract The paper will describe a number of new characteristic phenomena of sand under cyclic loading, which have been discovered by triaxial cell testing, at the Soil Mechanics Laboratory at Aalborg University using test specimens with equal height and diameter.

Regression Models for Validating Cyclic Triaxial Test Results

Geotechnical Testing Journal, 2011
Abstract Cyclic triaxial tests are commonly used to evaluate a soil’s potential for liquefaction during seismic events. Following testing, it is necessary to evaluate the validity of the test results. This can be a difficult task unless the engineer has previously acquired a reasonable amount of experience with this type of testing.

Cyclic Triaxial Strain-Controlled Testing of Liquefiable Sands

1988
Two series of undrained cyclic triaxial strain-controlled tests were performed on two different Imperial Valley, California, silty sands which liquefied during an earthquake in 1981. Both intact and reconstituted specimens were tested, and the testing procedures are described.

Unloading Elastic Behavior of Sand in Cyclic Triaxial Tests

Geotechnical Testing Journal, 2016
Abstract In this paper, digital image technology was used in the surface-deformation measurement of soil, making it possible to monitor the axial, radial, and volumetric deformations and the deformation distribution over the entire surface of specimens in triaxial tests.
