|Subjects: ||Elastic modulus|
|Issue Date: ||12-Dec-2006 |
|Citation: ||US Patent 7,149,634 B2. Washington, DC: US Patent and Trademark Office, 2006.|
|Abstract: ||A method and apparatus of determining an elastic modulus of a material having a Poisson's ratio v by a Berkovich indenter having an elastic modulus E; a Poisson's ratio v, and a cross sectional area A(h) as a function of depth are provided. The method and apparatus model the Berkovich indenter with a conical shape and a spherical cap.|
