Effect of prior cyclic damage on rock failure exposed to triaxial multistage unloading confining pressure and cyclic loads

Fatigue & Fracture of Engineering Materials & Structures, 2022
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.

Impacts of Initial Deviator Stress and Cyclic Confining Pressure on Mechanical Behaviors of Ningbo Clay under Cyclic Loading

International Journal of Geomechanics, 2021
Abstract The development of both accumulated axial strain and excess pore-water pressure under cyclic triaxial tests with and without cyclic confining pressure was the focus of the investigation.

Undrained cyclic triaxial behavior of saturated clays under variable confining pressure

Soil Dynamics and Earthquake Engineering, 2012
A 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.

Effect of confining pressure on the mechanical properties of heterogeneous rocks under cyclic loading

Physics of Fluids
To investigate the influence of mesoscopic heterogeneity and confining pressure on the mechanical properties of granite under cyclic loading, a series of biaxial compression tests were conducted on granite samples with different mineral crystal size distributions using Particle Flow Code (PFC) software.

Modeling permanent strains of granular soil under cyclic loading with variable confining pressure

Acta Geotechnica, 2019
Previous 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.
