Nano-Science is a multidisciplinary subject. Physics, chemistry, and material science are the main subjects which are the backbone of this new science. In application, many other subjects have some profound effects on nano-technology. Electronics, Pharmacy, Physiology and mechanics can be introduced as examples. The main aim of the current project is to model material concepts of nano-technology in the light of computational mechanics. The work has two main parts: First, finding an exact, scientific definition of the subject (analysis of mechanical properties for nano-material) and the second, application of finite element method for modeling of mechanical properties in nano-material. The models were improved then to find acceptable results.
