An alternative to the determination of the effective zero point in instrumented indentation: use of the slope of the indentation curve at indentation load values
Abstract : Most identification models based on instrumented indentation rely on the knowledge of the indentation load-penetration depth curve corresponding to the bulk material. Experimentally, and especially in the case of micro and nanoindentation testing, the measured curve can be affected by low scale artefacts such as sensor sensitivity, surface roughness, imperfect indenter tip geometry and material heterogeneity, leading to incorrect identifications of the indented material's bulk mechanical properties. This work proposes an exploitation of identification models which is based on the slope of the indentation curve at indentation load values and provides accurate results which are not affected by low scale artefacts.
