Numerical Identification of the Mechanical Behaviour of a Fluoroelastomer (FKM) Using Nanoindentation Test

The aim of the paper is to provide a numerical model of nanoindentation tests carried out on a synthetic elastomer. Some works deal with such numerical model but on classical elastomer like silicon rubber. Our study focuses on a filled fluoro-elastomer (FKM). At first, a 2D numerical model equivalent to a Berkovich test is built. The law of behaviour used in the simulation is obtained from the results of a single traction test. Then a numerical nanoindentation test can be carried out and compared with experimental nanoindentation curves of a previous study. The relevance of the most suitable laws of behaviour is deduced.
