Effects of fluid and aggregate fragmentation on dynamic concrete behavior using a novel DEM-based hydro-mechanical model
Abstract
This study examines the impact of fluid flow and aggregate fragmentation on the dynamic behavior of concrete under uniaxial compression at varying strain rates. Concrete was simulated as a four-phase material consisting of aggregate, mortar, ITZs, and macropores. The concrete mesostructure was obtained from laboratory micro-CT tests. 2D simulations were carried out. A novel, fully coupled DEM/CFD technique, based on a pore-scale thermal-hydro-mechanical model, was employed to predict the effects of strain rate, fluid flow, and aggregate fragmentation on the response of both partially and fully fluid-saturated concrete.
