Evaluations of Elasto-Plastic Properties and Fracture Strength Using Indentation Technique

Abstract:

Article Preview

Evaluations of elasto-plastic properties and fracture strength were studied utilizing indentation technique. The elasto-plastic properties of nine monolithic metals were estimated using dual indentation method and compared to the properties under tensile loading test. This method could predict stress - strain curve and was found to determine ultimate tensile strength. For brittle coating, fracture strength of diamond -like carbon (DLC) film was estimated by hybrid indentation with acoustic emission (AE), corrosion potential fluctuation (CPF) and finite element method (FEM). AE and CPF data provided information on the timing of film cracking and its mechanism. Fracture strength of the films could be evaluated using Vickers and Rockwell indentation.
