Prediction of Micro and Nano Indentation Size Effects from Spherical Indenters

Mechanics of Advanced Materials and Structures, 2012
In the present work, a micromechanical model based on dislocation mechanics for predicting indentation size effect from spherical indenters is developed and compared with the most widely used Swadener et al. (2002) model. The key idea proposed here while deriving the model is that a nonlinear coupling between the geometrically necessary dislocations ...

Indentation size effect during measuring the hardness of materials by pyramidal indenter

Materials Today: Proceedings, 2019
Abstract The influence of the indentation force on the manifestation of the indentation size effect when measuring Vickers hardness is investigated. It is shown that when introducing the Vickers pyramid, the deformation remains constant, and the main criteria for the indentation size effect are the resistance of the material to the deformation and ...

Origin of the size effect in indentation of metals

International Journal of Mechanical Sciences, 1991
Abstract A recently-proposed description of “the indentation size effect” in terms of a size-dependent error in effective load is shown to be accurate and to be consistent with a finite “plastic hinge” zone at the perimeter of the indentation. The implication for the theory of indentation is that strain-hardening materials do not deform in a size ...
