Numerical Simulation on Size Effect of Fracture Toughness of Concrete Based on Mesomechanics

Numerical Simulation on Size Effect of Fracture Toughness of Concrete Based on Mesomechanics

The fracture performance of concrete is size-dependent within a certain size range. A four-phase composite material numerical model of mesofracture considering a mortar matrix, coarse aggregates, an interfacial transition zone (ITZ) at the meso level and the initial defects of concrete was establish...
