Surface Roughness Effect on Dynamics of Carbon Nanotube

This paper deals with the dynamic response of a single-wall carbon nanotube (CNT) based on thin-walled shell mode. Following the subsequent motion of zigzag single-wall CNT under-surface roughness effect, a non-linear dynamic response may occur. The results carried out using Phase Plot through variation of surface roughness parameter which shows that the surface roughness parameter plays an important role in changing the regular motion into the chaotic. The principle point of interest is the conditions of significant interaction to occur and the increased chaos associated with the altered surface roughness parameter in zigzag CNT. The surface roughness parameter plays a significant role in changing the regular motion from revolution to liberation and infinite period separatrix for zigzag CNT which can be utilised for different application in engineering, environmental sciences, nanotechnology, tribology, medicines, pharmaceuticals and in industry.
