摘要
A finite element model of a microindentation is developed where the scanned surface topography data which represent the actual surface-roughness values are used in the construction of the finite element model of the workpiece. Indentation simulation with friction effect solely due to the surface deformation produces results which match the experimental ones in terms of residual indent size and pile-up heights. A roughness-dependent friction model is developed, which is comparable with the models proposed by Johnson (1985) and Alcala (2004).
