| Abstract Scope |
Indentation plastometry is promoted as a fast, reliable method for gaining mechanical property data using less material than traditional mechanical testing. Through use of an instrumented indentation test in conjunction with inverse finite element analysis (FEA) modeling, engineering and true stress-strain curves are fit using an established model (Voce). Because of the relatively small indenter size (0.5 - 1.0 mm diameter ball), structured indent patterns can be used to fully interrogate deep case-hardened surfaces or as-tested mechanical test samples. Inferred stress-strain results can be used to validate and refine component design choices. Indentation plastometry results will be reviewed for deep case-hardened components, as well as comparison to tensile test data from equivalent component locations. |
