Development of a Ball Indentation Test for Samples of Finite Thickness

Abstract

A spherical indentation test for small quantities of low modulus materials is described and experimentally validated. The data analysis takes into account finite sample thickness. Comparison with the Hertz contact theory is made, and extension to viscoelastic characterization is discussed.
