Notes:
The development of the instrumented indentation test (IIT), which gives accuratemeasurements of the continuous variation in indentation load as a function of depth, has paved theway to assessing tensile properties and residual stress in addition to hardness by analyzing theindentation load-depth curve. In this study, analytic models and procedures are presented forevaluating tensile flow properties and residual stress states using IIT. Tensile properties wereobtained by defining representative stress and strain beneath the spherical indenter. The evaluationof residual stress is based on the concepts that the deviatoric stress part of the residual stress affectsthe indentation load-depth curve, and that analyzing the difference between the residual stressinducedindentation curve and the residual stress-free curve permits evaluation of the quantitativeresidual stress in a target region
