| ABSTRACT In this paper, the effects of Carbon Nanotube (CNT) shape and distribution on crack growth in nanocomposites are investigated. Nanocomposites containing straight and sinusoidal CNTs with uniform and random distribution were investigated. Crack growth in these nanocomposites was investigated using finite element simulation and micromechanical models. Then, the contact surface between carbon nanotubes and the matrix was investigated. In addition, using the Maximum Tangential Stress (MTS) and the maximum energy release rate (G) criteria, fracture toughness values for the four nanocomposites under investigation are determined. Finally, the obtained results were compared with previous results, which were in good agreement. KEYWORDS Keywords: Nanocomposite; Contact surface; Crack growth; Finite elemant; Micromechanical.
