Fracture Behavior of Rocks with Different Grain Sizes Based on the Boundary Effect Model: Insights from AE and DIC

Zhe Dong, Zhonghui Li, Enyuan Wang, Xin Zhou et autres

Rock fracture behavior is strongly influenced by grain size and boundary effects, which complicate the determination of fracture parameters and the interpretation of size-dependent failure. This study investigates the fracture behavior of sandstone and diorite within the framework of the boundary effect …

Acoustic emission response characteristics and energy evolution laws of sandstone under stepwise cyclic loading with “loading–stress maintaining–unloading”

Quancong Zhang, Zhonghui Li, Yue Niu, Shan Yin et autres

The analysis of damage evolution during the dynamic process of stress accumulation–brief stabilization–stress transfer is crucial for ensuring the stability of underground engineering projects. In this study, sandstone specimens were subjected to a cyclic loading regime consisting of loading–stress maintaining–unloading phases. Mechanical …
