MULTISCALE MODELING FOR STATIC CONTACT PROBLEMS OF FOAMED AL

摘要：

Monte Carlo Methods were used to obtain the macroscopic structural model.Three scales were numerically simulated on the contact surface of the Al entity.The surface was macroscopically flat,and of self-affine fractal fluctuated at smaller scales.Lennard-Jones potential was used for simulating the atoms.Through onehuge-atom level,the process at atom level and the process at macroscale were associated by iterative relaxation.The results of the simulating of numerical specimen in the static elasticity obtained here do not show remarkable difference against the classical FE method.
