Investigation on the Creep Failure Mechanism of Sandy Mudstone Based on Micromesoscopic Mechanics by Xinshuai Shi, Hongwen Jing, Weiqiang Chen, Yuan Gao, Zhenlong Zhao

“…The 3D scanning technologies combining with the 3D reconstruction methods proved that the crack expansion path of crept specimens was more complicated, showing a more prominent asperity height and slope angle. Finally, a mesostrain dilating microelement model of the sandy mudstone specimen’s fracture surface was proposed to prove that the dilatancy effect would be more pronounced in the creep process.…”
