dc.description.abstractSome methods of evaluation of mechanical properties have been used for the determination of properties in coated systems. These methods include the indentation test as well as the scratch test, which is equally easy to perform and regularly does not require special preparation of the test bodies. The scratch test has been carried out experimentally and numerically for several decades to analyze the adhesion resistance and failure modes of hard and thin coatings deposited on metal substrates. The test allows to establish the relationship of normal load values with the failures in the system,in this way, the test delivers a quantitative measurement of the load for the failure of a coating deposited on a substrate. The failure modes associated with the scratch test have been identified based on observations and analysis of the groove created during the sliding of the indenter in a single scratch movement. The main objective of this study was to analyze, via simulation by finite elements method, the behavior of longitudinal S11 and transversal S33 stresses and the correspondence with the failure of a coated system, considering the contact and displacement of a hard particle and rigid in repetition of up to five cycles of scratching along the same groove. The results showed that is possible to establish that with the increase of the scratch cycles lateral cracks may still be present on the sides of the groove since. The stress values reached were always higher than the stress value imposed to the coating in the simulation model.en_US
