To study the acoustic characteristics and failure mode of the rock failure process under a
complex stress state, acoustic emission (AE) monitoring technology was employed to collect …

Rock salt is a common sedimentary rock found in the crust and is widely used for
underground energy storage and waste disposal. This research conducted multi-stage cyclic …

To obtain a comprehensive understanding of the difference between deep and shallow
rocks, and the damage evolution laws of a rock mass at different depths, a case study was …

The variation of pore structure results in a significant difference in physical–mechanical
properties within coral reef limestone (CRL). The acoustic emission (AE) and digital volume …

When salt caverns are used for the medium of underground energy storage, the surrounding
rock experiences cyclic loading due to periodical injection-production. The cyclic load …

This paper provides a comprehensive exploration of the research progress in the field of
rock statistical damage constitutive models. The introduction section highlights the …

Anticipating the progressive damage and strength of an anisotropic and interbedded rock
mass is challenging due to the overwhelming variables which need to be considered …

The existing micromechanical damage plasticity models assume that penny-shaped
microcracks are present in the rocks, but it is seldom a reality. These models result in the …

Acoustic emission (AE) signals on the eve of brittle failure in hard rock often indicate a quiet
period, ie, a significant decrease in the number of AE signals. To address the current …

Mineral grain size caused by the geological diagenetic process is one of the fundamental
reasons leading to the differences in rock mechanical behaviors, which brings challenges to …
