In this study, we have studied deformation and fracture behavior of composite materials composed of polyethylene (PE) and carbon nanotubes (CNTs) by using molecular dynamics method. First, compressive analysis is performed in the radial direction of two CNTs placed in the composite model. Then, multiaxial loading analysis is performed by tension or compression in the longitudinal direction of either CNT under the constant compressive stress in the radial direction. As a result, we revealed that compressive stresses to the radial direction of CNTs change the fracture strength under tension or compression to the longitudinal direction in composite models.
