Abstract:

The present subject matter discloses a method of measuring a peak load, including the steps of placing an indenter between a first surface and a second surface, exerting a load on at least one of the first and second surfaces, measuring at least one of a width, depth, radial chord length, and cross-sectional area of an indentation formed by the indenter in at least one of the first and second surfaces; and converting the measured parameter into a load value. Certain methods further include the steps of converting the measured parameter into a load per length value and obtaining a load value by integrating along a circumferential length of the indentation. In still other methods, the exerted load is a compressive load.
