Abstract

The methods of analysis described in Chapter 3 can be used to provide a useful computation of simulated load-displacement curves, where the mechanical properties of both the specimen and indenter are given as input parameters. A simulated load-displacement curve allows comparisons to be made with actual experimental data. For example, such comparisons may yield information about non-linear events such as cracking or phase changes that might occur with an actual specimen during an indentation test. In this chapter, the procedure for generating a simulated load-displacement curve is described in detail and a comparison is made with experimental data from materials with a wide range of ratio of modulus to hardness.
