Conventional Vickers and true instrumented indentation hardness determined by instrumented indentation tests
We evaluate Vickers hardness and true instrumented indentation test (IIT) hardness of 24 metals over a wide range of mechanical properties using just IIT parameters by taking into account the real contact morphology beneath the Vickers indenter. Correlating the conventional Vickers hardness, indentation contact morphology, and IIT parameters for the 24 metals reveals relationships between conta...
متن کاملDepth - sensing instrumented indentation with dual sharp
57 A methodology for interpreting instrumented sharp indentation with dual sharp indenters with different tip apex 58 angles is presented by recourse to computational modeling within the context of finite element analysis. The forward 59 problem predicts an indentation response from a given set of elasto-plastic properties, whereas the reverse analysis 60 seeks to extract elasto-plastic propert...

متن کاملFailure of brittle layers on polymeric substrates from Vickers indentation
A study is made of median crack evolution in brittle coatings subjected to sharp contacts. A model bilayer system consisting of a glass plate bonded to a polycarbonate base, with a Vickers pyramid as indenter, is used to demonstrate the evolution in situ. The cracks undergo a phase of stable downward growth with increasing load. Beyond the coating mid-plane, flexural stresses (coupled with the ...
