Numerical study of spherical indentation in superficial coatings
description The aim of this work was to simulate the indentation testing behaviour of a rigid ball indenter on a coating/substrate system by the finite element method. Indentation testing has been used for a long time to determinate the superficial hardness of different materials. Nowadays, a number of researchers have developed new techniques based on this testing to evaluate different mechanical properties of materials including fracture toughness and Young modulus. However, there are still limitations to analyze the coating/substrate system behaviour during indentation testing. To help to reduce those limitations, the present work uses the finite element technique to simulate stress and strain fields during the indentation cycle. A commercial finite element code which has been considered as a promising tool for non linear problems and fracture process was used. The numerical results for the stress and strain fields focused mainly in the indenter contact region and for interface between coating and substrate were calculated during the testing cycle. Furthermore, through the use of the maximum principal stress criterion, details of the failure mechanism that occurs on coating system were evaluated.
