Energy evolution and damage constitutive model for deep marble under triaxial compression

Frontiers in Earth Science
IntroductionHigh ground stress in deep mining operations results in rocks exhibiting mechanical properties that differ from those at shallow depths. This study conducted conventional triaxial compression (CTC) tests to elucidate themechanical behaviors ...

Modeling the initial mechanical response and yielding behavior of gelled crude oil

Open Physics, 2018
The initial mechanical response and yielding behavior of gelled crude oil under constant shear rate conditions were investigated. By putting the Maxwell mechanical analog and a special dashpot in parallel, a quasi-Jeffreys model was obtained. The kinetic

Energy Dissipation of Rock with Different Parallel Flaw Inclinations under Dynamic and Static Combined Loading

Mathematics, 2022
Deep surrounding rocks are highly statically stressed before mining (excavating) and will inevitably experience disturbances from unloading, mining, stress adjustment or their combinations during mechanical or blasting excavation, which actually suffer ...
