Three-Dimensional Finite Element Modeling for Concrete Materials Using Digital Image and Embedded Discontinuous Element
Get access
ABSTRACT
A three-dimensional finite element modeling is proposed to simulate mechanical behaviors of concrete materials subjected to macroscopic loadings. Concrete materials are modeled as two-phase composites consisting of coarse aggregates, mortar, and their interfaces in order to consider tensile failures. Digital image processing techniques are employed for finite element modeling, and a mixed formulation based on the assumed enhanced strain method is employed to model the interfacial discontinuities in a voxel finite element. Numerical comparisons between a real concrete model and two imitative models are made.
