| Title: | Method of determining elastic modulus | Authors: | Ma, DJ Ong, CW |
Issue Date: | 12-Dec-2006 | Source: | 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. | Rights: | Assignee: The Hong Kong Polytechnic Univeristy. |
