Abstract: The purpose of this study was to explore the influence and action mechanism of the stress amplitude on the evolution of the deformation behavior of sandstones during multilevel triaxial cyclic loading and unloading (CLU) ...

Abstract: To study the fatigue deformation and damage characteristics of sandstone during multilevel cyclic loading and unloading (MCLU) with varying lower limits of stress (VLLS), this research conducted an MCLU test with VLLS by ...

Abstract: Abstract To investigate the effects of multistage cyclic loading on sandstone under complex stress environments, uniaxial cyclic compression tests were conducted under different prestress conditions, incorporating acoustic ...
