Patents by Inventor Pierre Jean Morel

Pierre Jean Morel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Characteristic strain and fracture resistance for scratch independently of indenter geometry
    Patent number: 6945097
    Abstract: The invention involves an apparatus and method for calculating characteristics of materials, such as equivalent strain, using an indenter where the method used is independent of indenter geometry. The method includes performing a scratch test to calculate the strain for each of a plurality of indenter shapes, such as a theoretical sphere and cone, using known equations. The strain of a composite indenter, such as a cone with a rounded tip, can then be determined taking into account contributions from each of the plurality of theoretical shapes.
