| dc.description.resumo | Indentation Tests have been largely used for determination of superficial hardness. Due to its great applicability, new methodologies are being developed in order to determine mechanical properties such as Young Modulus (E) and fracture toughness (KIC) for brittle materials. However, the Vickers indentation has several limitations and complications as methodology for characterization of these material properties. Thus, the use of a numerical technique able to determine fields of stress and strain during the indentation cycle may give a more reliable interpretation of this kind of test. Hence, this work aims to study the mechanical behaviour of a specimen of tungsten carbide cobalt (WC-Co) during a Vickers indentation test, based on FE calculations with the commercial solver MSC Marc. In a future development of this work, it will be developed numerical models to simulate the mechanisms of crack onset and their propagation during the tests. | pt_BR |
