ABSTRACT: I will report on computer simulations of nano-indentation into amorphous polymer films. I will concentrate on the initial, kinetic stage of the indentation process and give results for the motion of the indenter, the deformation field of the polymer film, the stress field, and the field of total monomer energy. I will propose an effective coefficient as a new measure for the resistivity of a surface against indentation. Its value can be determined in an experiment with constant indentation velocity. I also will talk on an investigation into the free drift behavior when the external driving force has been set to zero and the tool is expelled from the polymer film. For different polymer chain lengths, the tool's motion is exponential in time and one can determine the relaxation scale.
