Effect of Pile-Up on the Mechanical Characteristics of Steel by Depth Sensing Indentation

Popis výsledku v původním jazyce

Instrumented indentation testing (IIT) is a technique for measuring the mechanical properties of materials. IIT is particularly well suited for testing small volumes of material such as thin films, particles, or other small features. It is most commonlyused to measure Young?s modulus E and hardness H. All of the advantages of IIT derive from this continuous measurement of force and displacement. In order to interpret the contact mechanical property from the nanoindentation curve, a micromechanical model has been developed by Oliver Pharr. However, the The Oliver Pharr method assumes that the contact periphery sinks in, which limits the applicability to the materials pile up. There is to the materials pile up the contact area is larger than assumed elastic contact theory (material falls within a purely elastic contact), and therefore leads to an overestimation of H and E [1]. It is therefore important to determine the effect of materials pile up on the mechanical properties by instrume
