Employing these two types of equipment applying contrasting stress path regimes, a series of cyclic undrained laboratory tests was conducted on reconstituted sandy clay specimens at varying frequencies (f = 0.1–1 Hz) and cyclic stress ratios (CSR = 0.2–0.3). The hollow cylinder test results have shown that higher CSR values and lower frequencies induce greater permanent deformations and excess pore water pressures at a given number of loading cycles (N). For CSR = 0.2, pore pressures and axial strains were found to increase even after a large number of cycles (N = 50,000). However, when the higher CSR value of 0.3 was imposed, the soil failed in less than 300 cycles by reaching 5% of axial strain. Undoubtedly, PSR adversely affected the accumulation of axial strains and soil degradation, whereas in contrast, the development of pore water pressure was less influenced by PSR.]]> Mon 19 Sep 2022 15:12:28 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53209 Fri 17 Nov 2023 11:40:57 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54687 Fri 08 Mar 2024 11:52:58 AEDT ]]>
