Abstract
A state-of-the-art finite element program (MARCTM) is used to derive as much information as possible from the simulation of a 136 degree(s) wedge indentation into multilayer systems. The deformed specimen is compared with experimentally found results as far as an experiment, i.e., a hardness indentation, yields measurable parameters. We suppose some of the surplus information obtained by the simulation to be reliable as well. A first step is undertaken toward the aim of obtaining elastic constants from a hardness or load-depth measurement in multi-phase films.
