The results show that the dynamic uniaxial and triaxial compressive strengths of the sandstone will linearly increase with the logarithm of the stain rate. Under approximately the same strain rate, the dynamic triaxial compressive strength will linearly increase with the confining pressure. Although the peak strain has no dependence on the confining pressure, it will generally increase with the strain rate. The secant modulus is independent of the strain rate and confining pressure. Three trend diagrams, which reflect the influences of strain rate or confining pressure on the dynamic mechanical properties of sandstone in the uniaxial and triaxial compression tests, are given, and the correlation between the failure modes of the sandstone specimens and the characteristics of the stress-strain curves is also analyzed.]]> Mon 23 Jan 2023 14:21:30 AEDT ]]> Dynamic Mohr-Coulomb and Hoek-Brown strength criteria of sandstone at high strain rates https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47877 Fri 03 Feb 2023 15:31:58 AEDT ]]>
