DEM and multi-level force chain network analysis of aggregate-strength effect on the splitting-tensile fracture behaviors of concrete under dynamic loading

Key Points

• Splitting-tensile fracture behavior changes significantly under dynamic loading conditions.
• Dynamic loading leads to increased fracture susceptibility, particularly with varying aggregate strengths.
• Analysis using discrete element method (DEM) evaluates the force chain network in concrete.
• Findings highlight potential for enhancing concrete performance based on fracture mechanics.
