Mechanical responses and failure characteristics of longmaxi formation shale under real-time high temperature and high-stress coupling
ENGINEERING FAILURE ANALYSIS(2023)
Abstract
•Mechanical responses and failure characteristics of Longmaxi Formation shale were revealed.•Acoustic emission (AE) evolution of Longmaxi Formation shale during triaxial compression test was described.•Micro-mechanism of improving ductility by high confining pressure and real-time high temperature is different.
