An investigation of nanoindentation tests on the single crystal copper thin film via an AFM and MD simulation [PDF]
, 2007 Nanoindentation tests performed in an atomic force microscope have been utilized to directly measure the mechanical properties of single crystal metal thin films fabricated by the vacuum vapor deposition technique. Nanoindentation tests were conducted at

Determination of the optimum ball radius for researching materials using ball indenting
Космические аппараты и технологии, 2021 The article discusses the study of the effect of a change in the radius of the ball in the injecting of the sample on the curve in the coordinates «load – indentation depth», the deviation of the indentation depth during elastoplastic indentation from ...

The Correlation of Indentation Size Effect Experiments with Pyramidal and Spherical Indenters [PDF]
MRS Proceedings, 2001 ABSTRACTExperiments were conducted in annealed iridium using pyramidal and spherical indenters over a wide range of load. For a Berkovich pyramidal indenter, the hardness increased with decreasing depth of penetration. However, for spherical indenters, hardness increased with decreasing sphere radius.

Hardness-Depth Relationship with Temperature Effect for Single Crystals—A Theoretical Analysis
Crystals, 2020 In this paper, a mechanistic model is developed to address the effect of temperature on the hardness-depth relationship of single crystals. Two fundamental hardening mechanisms are considered in the hardness model, including the temperature dependent ...

Size Effect of Aluminum Honeycomb Under Quasi-static Indentation
Taiyuan Ligong Daxue xuebao, 2021 In this paper, three different shapes of indenters were used to perform quasi-static out-of-plane uniaxial compression and indentation tests on three commercial hexagonal aluminum honeycombs with different densities. In order to distinguish the different

The Indentation Size Effect (ISE) of Ag–Cu Alloys
Crystals, 2023 The literature regarding the Indentation Size Effect (ISE) in metal alloys is scarce. The content of this article is the study of the relationship between the applied load and the measured values of the Vickers micro-hardness of silver and copper alloys,

The influence of indenter tip rounding on the indentation size effect [PDF]
Acta Materialia, 2010 Abstract A model was developed to interpret the indentation size effect (ISE). The model considers the tip wear effect, causing a rounded tip, the plastic zone size and various strengthening contributions, including geometrically necessary dislocations, pre-existing statistically stored dislocations and grain size.

Indentation Size Effect in Electrodeposited Nickel with Different Grain Size and Crystal Orientation
Crystals, 2023 Indentation size effect at shallow indentation depths still remains a challenge as it cannot be correctly described by the Nix–Gao model based on the concept of strain gradient plasticity and geometrically necessary dislocations.
