Abstract:

The ultimate objective of instrumented indentation testing is to obtain absolute measurements of material properties and behavior. To achieve this goal, accurate knowledge of the shape of the indenter tip is required. For indentation measurements involving sub-micrometer scale contacts, accurate knowledge of the tip shape can be difficult to achieve. In this paper, a technique referred to as blind reconstruction is applied to the measurement of tip shapes of indenters used with the atomic force microscope to indent polymeric materials.
