“…Despite the decrease in effective mean stress acting on the grains, some studies revealed the occurrence of particle crushing in undrained monotonic tests. Hyodo et al (1996) confirmed the occurrence of breakage of Masado and Shirasu soil after undrained monotonic tests at low confining pressures. Several researchers Bopp and Lade 2005;Shahnazari and Rezvani 2013) illustrated that the degree of particle crushing in undrained tests was lower compared to the drained tests because the D r a f t effective mean stress sustained by soil particles was lower.…”

A series of undrained monotonic and cyclic triaxial tests were performed on silica sand at two initial densities and different confining pressures from 0.1 to 5 MPa to investigate their shear response and crushing behaviour. The influence of particle crushing on the undrained shear strength and pore-water pressure was examined. To clarify the evolution of particle crushing, undrained monotonic and cyclic tests were terminated at several distinctive stages and sieving analysis tests were subsequently performed on the tested specimens. In the undrained monotonic test, specimens exhibited remarkable dilation behaviour and experienced no apparent particle crushing at low confining pressures. An increase in the mean stress suppressed the dilatancy due to a faster increase of the pore-water pressure, giving rise to the occurrence of particle crushing. In the undrained cyclic test, a higher confining pressure and cyclic stress ratio resulted in a much higher relative breakage. At a specific cyclic stress ratio, the relative breakage increased as the cyclic loading progressed. The confining pressure and shear strain amplitude played a significant role in controlling the evolution of particle breakage. The correlation between the relative breakage and plastic work for specimens under isotropic consolidation, undrained monotonic, and cyclic loadings has been validated experimentally.
