| Research Abstract |
Imitating frictional phenomena between solid surfaces had been difficult since the surface shape in atomic level affected the phenomena. In this work, interactions between surface atoms obtained in molecular simulations are used as interaction between surface particles in particle method. As a result of such friction simulations for fractal surfaces, friction constants which were similar to experimental values were obtained.
