Abstract: Carbon nanotubes have excellent mechanical properties that make them ideal reinforcing materials, lab Researches observed crack bridging, bonding and fiber pullout in CNT/cement composites, these results paved the way to analytical and numerical studies based on continuum mechanics, molecular dynamics and the Finite element method. This study is the introduction to multiple modeling approaches and analysis using the finite element method, our first step is to understand the effect of the addition of SWNT in a concrete matrix and its benefits, the next steps will be analyzing the fracture behavior of the composite, which will be discussed in future studies. The FEM is used to estimate the longitudinal elastic modulus of the composite, large-scale models were developed, simulating SWNTs using pipe elements in ABAQUS. With a deflection simulation test in FEM, Results from finite element simulations were compared to the analytical results (rule of mixtures) and validated.
