Permanent deformation in terms of rutting is a major deterioration mode of bituminous bound pavements. The triaxial cyclic compression test (TCCT) is a scientifically accepted and standardised test method to assess the resistance to permanent deformation. Presently, the standard TCCT according to EN 12697-25 is carried out with cyclic axial loading and

Measurement of Cartilage Fluid Pressurization in Confined Compression Cyclical Loading
Advances in Bioengineering, 1998Abstract In recent studies (Oloyede and Broom, 1991; Soltz and Ateshian, 1997, 1998) it has been demonstrated from experiment and theory that compressive stresses applied across the surface of articular cartilage are supported primarily by the hydrostatic pressurization of the interstitial fluid, under configurations of confined ...

Undrained cyclic triaxial behavior of saturated clays under variable confining pressure
Soil Dynamics and Earthquake Engineering, 2012A laboratory study on the undrained dynamic behavior of saturated clays in cyclic triaxial tests with a variable confining pressure (VCP tests) is presented. Tests were performed on remolded clayey samples using a dynamic triaxial device where the deviatoric stress and confining pressure can be varied simultaneously.

AbstractA series of triaxial alternative unloading and damage‐controlled cyclic loading tests were conducted on deeply buried granodiorite. The testing results reveal that the prior cyclic loading damage influences rock volumetric deformation, stiffness degradation, damage evolution, and failure modes.

Effects of cyclic confining pressure on the deformation characteristics of natural soft clay
Soil Dynamics and Earthquake Engineering, 2015Abstract To investigate the coupling effects of cyclic deviator stress and cyclic confining pressure on the deformation behavior of natural soft clay under partially-drained conditions, a series of one-way cyclic triaxial tests with and without cyclic confining pressure were carried out.

Modeling permanent strains of granular soil under cyclic loading with variable confining pressure
Acta Geotechnica, 2019Previous experimental studies showed that variable confining pressure (VCP) promoted the development of permanent strains of granular soils in most cases and indicated VCP should not be ignored. However, existing empirical formulas do not fully account for the effect of VCP on permanent strains.

Possible Stress Path of HCA for Cyclic Principal Stress Rotation under Constant Confining Pressures
International Journal of Geomechanics, 2007Nowadays most hollow cylinder apparatus (HCA) in the world can only apply two dynamic loads, namely the axial load (W) and torque ( MT ) , during cyclic principal stress rotation. The limitation of this loading mode is presented, and based on such limitation other possible and applicable loading modes are put forward: (1) On the premise of setting W a ...
