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
