Investigation on the Damage Process and the Deformation of Concrete Using Meso Element Equivalent Method

Abstract:

The meso-element equivalent method (MEEM), is developed in the study to investigate the damage process and the macro-mechanical properties of concrete. The Monte Carlo method is adopted to generate the random aggregate structure (RAS) firstly, and then the characteristic element size is applied to divide the RAS into many identical units. Each unit obtained is processed equivalently to be a homogeneous and isotropic unit by the homogenization theory. Some concrete specimens in 2-D and 3-D are undertaken to verify the feasibility and accuracy of the proposed approach. The results indicate the high efficiency and accuracy of the present methodology.
