Abstract: The problem of using the mechanical properties determined in a macroexperiment in contact models for micron-sized roughness elements is considered. For a sample of commercial-purity AD1 aluminum, the penetration depths of an indenter into a rough surface element that are determined in a physical experiment and in a three-dimensional finite element simulation are compared. It is found that, with allowance for certain assumptions, the application of the properties determined in a macroexperiment requires their correction to take into account the cold work hardening of the surface layer in the sample material and the size effect.
