With the necessity of developments of modern science and technology, the size ofmicrostructure tends to a molecular scale and a new discipline of so called nanotechnology hasbeen founded. Nanomechanics is one of important branches of nanotechnology.The researchemphases are mainly placed on the behavior and variation of matters in nano-scale, and the effectsof these behavior and variation on the macro-properties of matters. There exist in nano-scalematters many special effects, such as quantum effect, micro-scale effect and so on. These specialeffects would result in related special properties and behaviors of matters. At present, the mainmethods to learn the nano-scale effects are numerical simulation and experimental investigation.In the present paper, recent advances of Molecular Dynamics and Monte Carlo simulations arereviewed; the interesting problems in nanomechanics and the trends of the numerical methods ofnanomechanics are discussed. Based on quantum mechanics, with hybridizing muti-discipline andconsidering the hierarchy of matters one may find a feasible way to develop some research methodsof nanomechanics.
