Abstract: In the present paper, the potential use of a rotating indenter is discussed. Fundamental basics of the theoretical background for normal and torque loads on layered materials are presented, and the influence of certain material parameters on the hypothetic measurement results is investigated. It will be shown that an indenter with combined normal and torque load facilities (with its axis of revolution identical to the axis of normal indentation) would not only overcome the problem of detecting effects such as pile-up and sink-in, but also allow the determination of additional material properties such as, e.g., intrinsic surface stresses.

Keywords: surface testing; nanoindentation; rotational loading; thin films; Young|s modulus; intrinsic stress; rotating indenter; surface stresses.
