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

Journal 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.

SANDY SOILS DYNAMIC STRENGTH PARAMETERS ACCORDING TO TRIAXIAL TESTS

Engineering Geology World, 2019
Correct determination of strength properties is always relevant for the prediction of the mechanical behavior of soils and their massifs. Under static loading conditions, the issue is prominent in domestic and foreign literature, but the determination of strength properties under dynamic loading causes theoretical and methodical issues.
