ABSTRACT:
A method is provided for determining Young's modulus and, if desired, Poisson's ratio of a coating on a substrate wherein load-displacement indentation data in the elastic region (either elastic loading or unloading) generated using an indenter is analyzed to interpret the elastic repsonse of a coated material. The data analysis pursuant to the invention is based on an extended Hertzian analysis developed for thin-film coatings.
