Experimental and Numerical Studies on Dynamic Response and Fracture Characteristic of Sandstone with Multiple Defects

Geological discontinuities (e.g., cracks, joints, faults, and cavities) fundamentally alter the integrity and mechanical behavior of rock masses. Under dynamic loading, such discontinuities induce stress concentration, disturb stress-wave propagation, and govern crack evolution, thereby acting as critical triggers fo...

Study on the Dynamic Mechanical Properties and Constitutive Model of Magnetite Specimens under Impact Loading

Blasting operations during open-pit mining can cause cumulative degradation of slope stability, increasing the likelihood of slope failures. This study investigates the dynamic behaviour and crack-propagation characteristics of rock masses in steep open-pit slopes under impact loading. Magnetite specimens from an open-...

Numerical Investigation of Rock–Backfill Composite Fracture Evolution Laws Under Deep Mining and Filling Stress Paths

Fracture evolution of rock–backfill composites (RBCs) under complex loading–unloading and dynamic disturbances is critical for stope stability in deep backfill mining. Using PFC3D, this study constructs numerical models of RBCs to investigate this process, considering burial depths (500, 1000, 1500, 2000 m), interface...

Effects of Strain Rate and Stress-State Dependence on the Mechanical Behavior of Calcareous Sand

The impact behavior of calcareous sand is critical in geotechnical and protective engineering. This study investigates the response of calcareous sand under triaxial stress conditions using an improved actively confined split Hopkinson pressure bar (SHPB) apparatus. The microscopic mechanism was revealed through the...

Maximum aggregate size effects on fracture parameters and crack extensions in recycled aggregate concrete: Experimental and predictions

The use of recycled aggregates in concrete can lead to structural differences, which in turn affect its fracture behavior. These differences are expected to influence crack propagation and fracture parameters. Therefore, investigating the crack behavior of recycled aggregate concrete (RAC) and applying fracture mec...

Influence of fissure angle and loading rate on sandstone failure mechanisms: implications for underground engineering stability

This study investigated the influence of fissure angle and loading rate on the stability of flawed rock masses. Uniaxial compression tests were conducted on sandstone specimens containing a single hole and double fissures, monitored simultaneously by acoustic emission (AE) and digital image correlation (DIC). The cou...
