The use of DMA for indentation
measurements has already been reported in the literature (ref.
Several methodologies have been introduced to estimate residual stress using instrumented indentation
. The earliest effort was to examine the relationship between hardness and residual stress.
tests (nanoindentation and AFM) were carried out with the same protocol as previously discussed.
From the literature review it concludes that Ball Indentation
test provides methodology for calculation of plane strain facture toughness which is essentially meant for conservative design of thick components.
There were many methodologies for the extraction of flow stress with the spherical indentation
The aforementioned studies indicated that indentation
efficiency is significantly determined by the crack propagation caused by indentations
of thin layer by spherical indenters has been commonly studied in the literature using either cumbersome numerical calculations or analytical modeling [11-14].
Residual imprints after indentation
with 1N load on commercially produced state-of-the-art protective coatings are shown in Figures 1(a), 1(b), and 1(c).
5, left) at the edge of the indentation
. This type of cohesive damage was not as significant as that observed in the other samples.
In 1859, earliest forms of static indentation
tests were introduced.4 Indentation
tests are generally based on the formation of indentation
on the surface of a metal or ceramic and hardness is established by gauging the perpetual depth of the indentation
and the applied load.5 Generally, the indentation
hardness may be described in terms of plastic and, to a lesser extent, the elastic properties of the metal or ceramic concerned.
The FISCHERSCOPE HM2000 with its ESP (Enhanced Stiffness Procedure) mode is able to determine mechanical properties like the Vickers hardness or the elastic indentation
modulus dependent upon the depth.
