Investigating the Interacting Mechanisms of Precast Intersecting Cracks in Concrete: Insights from the Simulations Based on Discrete Element Method

Underground mines often use shotcrete and reinforced concrete as support. Excavation disturbance, in situ stress, and blasting cause initial fractures to propagate. Intersecting fractures are common. This paper studies how intersecting fracture geometry affects fracture propagation under uniaxial compression. DEM and P...

Numerical Simulation of Crack Propagation in Concrete with Prefabricated Array Fractures Based on the Discrete Element Method

Concrete readily develops cracks under service loads, which poses severe risks to the overall safety of engineering structures. In this work, the discrete element method (DEM) integrated with PFC2D 5.0 numerical software is adopted to construct a mesoscale concrete numerical model containing pre-existing internal fract...
