The Impact of Aggregates Distribution on Concrete Failure

Abstract:

As the key component, the aggregates have a significant impact on the concrete’s mechanical properties and fracture modes. To study the impact of aggregates distribution on concrete failure, the extended finite element method (XFEM) is adopted to simulate the mesostructure failure process by virtue of random aggregate model under uniaxial tension. The result shows that aggregates distribution has little effect on the concrete mechanical properties, but aggregates distribution effect fracture modes.
