Study on Size Effect in Indentation Tests
Coatings, 2022 The depth dependence of the indentation hardness, i.e., the indentation size effect (ISE), was manifested as an increase or decrease in hardness when penetration depth decreases, which was observed by previous experiments. Most scholars believe it is generated by strain gradient.

INDENTATION SIZE EFFECT OF HEAT TREATED ALUMINUM ALLOY
Acta Metallurgica Slovaca, 2019 The aim of the submitted work is to study the influence of applied loads ranging from 0.09807 N to 0.9807 N on measured values of micro-hardness of heat treated aluminum alloy 6082. The influence of applied load on a measured value of micro-hardness was

Deformation mechanisms in a TiNi shape memory alloy during cyclic loading [PDF]
, 2012 The deformation mechanisms governing the cyclic stress-strain behaviour of a TiNi shape memory alloy were investigated in this work. To understand the development of these mechanisms during cyclic loading, three low-cycle fatigue tests were performed and

Nanoindentation of zirconium based bulk metallic glass and its nanomechanical properties
Journal of Materials Research and Technology, 2020 Nanoindentation experiments with a Berkovich tip are performed on zirconium based bulk metallic glass (Zr-BMG, Zr65Cu15Al10Ni10) to study its deformation and mechanical properties (elastic modulus and hardness) at nanoscale. Further to reveal indentation-

Cloaking by coating: How effectively does a thin, stiff coating hide a soft substrate?
, 2020 From human tissue to fruits, many soft materials are coated by a thin layer of a stiffer material. While the primary role of such a coating is often to protect the softer material, the thin, stiff coating also has an important effect on the mechanical ...
