| Abstract: | The mechanical behavior of highly oriented pyrolyti c graphite (HOPG) has been investigated in this paper, by simulating a machining p rocess in a nano-indent test with the method of molecular dynamics (MD) and by doing an experiment directly using the probe tip of atomic force microscope (AFM ) as tool. The characteristics and properties of graphite crystal lattice are di scussed firstly, then, three potentials are selected for different interaction b etween graphite atoms according to the graphite prope... |
