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

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.

Indentation Load-Size Effect in Al2O3 — SIC Nanocomposites [PDF]
Journal of Electrical Engineering, 2010 Indentation Load-Size Effect in Al2O3 — SIC Nanocomposites The indentation load-size effect (ISE) in Vickers hardness of Al2O3 and Al2O3 + SiC nanocomposites has been investigated and analysed using Meyer law, proportional specimen resistance (PSR) model and modified proportional specimen resistance (MPSR) model. The strongest ISE was found for

On the indentation size effect in spherical indentation
Philosophical Magazine, 2006 Size effects in plasticity at small length scales have been widely reported in a variety of loading situations. The hardness size effect has often been cited as an archetypal example. The indentation size effect was clearly demonstrated by Lim and Chaudhri (1999) in spherical indentation experiments on Copper and subsequently in experiments on Iridium ...
