The Influence of the Degree of Tension and Compression of Aluminum on the Indentation Size Effect (ISE)

Metals, 2022
The presented work deals with the relationship between the degree of cold plastic deformation (up to 84.5% in the tensile test and up to 83.5% in compression) and the parameters of the Indentation Size Effect (ISE). The tested material was 99.5% aluminum.

On the interpretation of the indentation size effect (ISE) through gradient theory for Vickers and Berkovich indenters

Journal of the Mechanical Behavior of Materials, 2016
The so-called indentation size effect (ISE) observed mainly in nanoindentation measurements with prismatic tips, is theoretically modeled in this article with the use of gradient theory. It is shown that the ISE, i.e.

On the novel finding of two modified-Nix-Gao models for indentation size effect [PDF]

Scientific Reports
Existing modified-Nix-Gao models have been developed to accurately describe the descending indentation size effect (ISE). This raises the question of whether the modified-Nix-Gao models can describe other types of ISE. In this paper, because Nix-Gao-Feng

Indentation size effect and hardness of materials [PDF]

E3S Web of Conferences, 2023
In recent decades, the Indentation Size Effect (ISE), which manifests itself as a change in fixed hardness depending on indentation conditions, has become one of the most urgent problems of modern materials science.
