Abstract

Abstract

The concrete is considered as a three-phase composite composed of matrix, aggregate and interface between them, and its mesoscale structure is represented with random aggregate model by using Monte-Carlo method. Then, the bilinear damage evolution model is adopted to describe the meso-element. s damage degradation, and the failure mechanism of wet screened, three-graded, four-graded concrete specimens under uniaxial compression is simulated with nonlinear finite element method. Furthermore, size effect on the strength is analyzed in the paper. The results show that the numerical solutions are fitted with experiment results, and the fracture of concrete is generally generated along the bond between aggregate and matrix, Cracks are extended in a direction parallel to the maximum compression stress.
