comparison of fracture behavior between nanocomposites reinforced with straight and sinusoidal carbon nanotubes

This research focuses on the impact of carbon nanotube geometry and dispersion on fracture behavior within nanocomposite materials. specifically, straight and sinusoidal configurations were investigated under both ordered and disordered spatial arrangements. the analysis employed finite element methods and micromechanical techniques to explore crack propagation paths and evaluate interactions at the carbon nanotube-matrix interface. fracture toughness across the four configurations was assessed based on the maximum tangential stress criterion and the maximum energy release rate. the study concludes with a comparative evaluation of the findings and previously published results, confirming the reliability of the proposed modeling approach.
