Assessment of cyclic deformation and critical stress amplitude of jointed rocks via cyclic triaxial testing [PDF]

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
Jointed rock specimens with a natural replicated joint surface oriented at a mean dip angle of 60° were prepared, and a series of cyclic triaxial tests was performed at different confining pressures and cyclic deviatoric stress amplitudes.

Cyclic triaxial tests on bituminous mixtures [PDF]

open access: yesRoad Materials and Pavement Design, 2014
In the framework of a study on rutting of bituminous layers, thermo-controlled triaxial tests under constant confining pressure on homogeneous asphalt concrete specimen have been performed. These tests are cyclic sinusoidal tests, with the aim to reproduce in some way the loading and unloading phases due to traffic on roads.

Comparison of sand liquefaction in cyclic triaxial and simple shear tests

open access: yesSoils and Foundations, 2021
The liquefaction resistance and correction factors Kσ and Kα of Nakdong River sand obtained from cyclic triaxial (CTX) tests were compared with those determined by cyclic simple shear (CSS) tests to ascertain the importance of the reduction factor Cr and

Testing noncohesive geogrid-reinforced soil in triaxial shear apparatus under cyclic loading

open access: yesGrađevinar, 2021
In road base layers, geogrids assume the reinforcement or stabilization function where good interaction between geogrid and unbound base material is important.

Energy Evolution and Fractal Characteristics of Sandstones Under True Triaxial Cyclic Loading and Unloading

open access: yesFractal and Fractional
To study the fractal characteristics and energy evolution of sandstones under true three-dimensional stress states, a true triaxial compression test and a cyclic loading and unloading test of sandstone specimens under different loads were carried out ...

Cyclic Triaxial Testing: A Primer

open access: yesJ
Cyclic triaxial tests are frequently used in the laboratory to assess the liquefaction susceptibility of soils. This paper will serve a two-fold purpose: First, it will serve to explain how the mechanics of the tests represent the stresses that occur in ...

Experimental study on the mechanical properties and deformation failure characteristics of sandstone under graded equal amplitude cyclic loading and unloading [PDF]

open access: yesScientific Reports
To investigate the effects of graded equal amplitude cyclic loading on rock deformation and failure, this study examines the influence of confining pressure and upper limit cyclic stress on the deformation parameters, stress–strain hysteresis curves, and

Cyclic Behavior of Calcareous Sand from the South China Sea

open access: yesJournal of Marine Science and Engineering, 2021
This study examines the cyclic behavior of calcareous sand obtained from the South China Sea. A series of undrained cyclic triaxial tests were performed on the calcareous sand with various relative densities, cyclic stress ratios, and effective confining
