The dynamic deflections of geometrically different single-walled carbon nanotubes are determined under various high-velocity impacts and for different positions at which ballistic impact is applied. Elastic beam model is applied to study the dynamic deflection of single-walled carbon nanotubes for two cases of boundary conditions, namely to clamped–clamped and clamped-free single-walled carbon nanotubes. Moreover, we examine the relationship between the single-walled carbon nanotube radius, the relative position at which the ballistic impact takes place, the speed of the object (e.g., bullet) that strikes the nanotube, and the deflection of the nanotube for a specific bullet size and shape as was used by recent study in the literature.
