Abstract Tensile properties of single-walled carbon nanotubes (SWCNTs) have been determined using molecular dynamics (MD) simulation. AtomsK® was used to generate the LAMMPS data file, and OVITO visualize dump file. The study examined how temperature, strain rate, size CNT, chirality, boundary conditions might affect tensile characteristics a typical SWCNT. Five intermediate temperatures were chosen: 300 K, 350 400 450 500 K. findings showed that strength decreased when temperature rose due structural changes, thermally induced faults, thermal deterioration, expansion. To further examine rate affects behavior material at three rates 0.25x10 − 3 Ps 1 , 0.5x10 1x10 selected. It shown SWCNT networks displayed rate-dependent behavior, with greater resulting in higher values; this feature is known as sensitivity. also observed for different sizes CNT. From computational results, it can be concluded increasing radius Also, mechanical chirality compared. armchair arrangement than zig-zag orientation.
