Modelamiento del ensayo de nanoindentación en una película de DLC (Diamond Like Carbon) mediante elementos finitos

Abstract

The study focused on simulating a nanoindentation test performed on a DLC (Diamond Like Carbon) film by means of finite element analysis (FEM), preserving the geometrical characteristics and main parameters of the experimental nanoindentation test. For this purpose, the research was divided into 3 stages; the first one focused on reviewing background and similar studies that allowed determining considerations and mechanical properties of materials similar to the one evaluated. In the second stage, the load-displacement (P-h) curve of the experimental test was analyzed to calculate Young's modulus and hardness for the DLC film. In the third step, 57 simulations were carried out where the information extracted from the ANSYS software was analyzed from different perspectives, validating that the methodology proposed in this work is recommended to simulate nanoindentation tests.
