چکیده:

In this paper, a hybrid atomistic-structural element for studying the mechanical behaviour of carbon nanostructures is introduced. The approach is based on inter-atomic potential functions and is capable of taking the non-linear nature of inter-atomic forces into account. Also, by applying the non-linear finite element methods, the effects of large deformations can be studied. Using this element-based non-linear method, the stability analysis of carbon nanotubes is performed and the post-buckling behaviour is predicted.
