    Abstract:

    Carbon nanotubes (CNTs) are the basic building blocks of nanocomposites for preparing high strength low weight material to be used for the future sustainable development. These can be used in aerospace industry as well as civil engineering. However, as their nano scale behavior is still to be understood in a better way, it is necessary to look much deeper into the material through atomistic simulation. By knowing the proper science to model nanoscale object, we can find out many interesting and fruitful results which can lead us to the better understanding of their proper usage. This topic gives a detail method of modeling and simulation of various kinds of CNTs like single walled, double walled, multi walled tubes as well as CNT ropes i.e. natube bundle with and without defects. The output of the study is fascinating mechanical characteristics of the CNTs. Here the properties are studied under various kinds of external loading. About 1 TPa of Youngs modulus with around 100 GPa of tensile strength is reported here. The bending, buckling and failure mechanism are modeled and captured as snapshots. Chirality dependent change of behavior and also defect related modified properties are established in this study. The study is an optimistic step towards building of super strong composite materials where the properties of the CNTs can be tailored according to our choice.
