Authors: Ma, Dejun
Ong, C. W.
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.
