Because of the 195 ^m broad displacement and the 760.34 Hz high first-order frequency, the proposed mechanism has potential applications under large indentation
depth-and-high frequency conditions.
The fact that the samples were porous and had rough surfaces ruled out the use of micrometer (and lower) scale indentation
techniques, such as the Oliver-Pharr method (ref.
The newly developed 'Enhanced Anti-indentation Deep Groove Ball Bearing' features special surface modification during the heat treatment process, which has reduced the Brinell Indentation
depth, an index for static load capacity, to 1/2 compared to that of standard heat treatment.
has been used to measure the mechanical properties of materials [2-7], such as hardness H, elastic modulus E, strain-hardening exponent n, and yield strength [[delta].sub.y].
was performed using a Platform 3 indenter (Micromaterials, Wrexham).
SEMPID (Software for the Extraction of Material Properties from Indentation
Data) package with evaluation of plasticity parameter and approaches for characterization of creep has been developed by Gorden Laboratory in recent years.
Has conducted ball indentation
test to study the elastic/plastic deformation behavior of aluminum 2024 .
The instrumented indentation
technique consists of applying load to the sample by means of an indenter of known geometry, while the applied load and the penetration depth of the indenter are recorded simultaneously during a loading and unloading cycle.
by excavation tools have been widely used to simulate the rock breakage process that determines the indentation
However, AFM-based quantification of the biomechanical property requires an appropriate rheological model which could describe the factual situation of cell indentation
. Although Hertz contact model is frequently used to interpret the experimental data obtained by AFM indentation
, one of its main assumptions, that is, treating indented cell as semi-infinite space, might be contradicted by the film morphology of cells after being removed from their native environment [6,7].
Thin lamellar cross sections for TEM observations were prepared using a focused ion beam (FIB) in the SEM from two locations in each sample: an undisturbed layer and a central region of residual indentation
imprint which was made using Fischerscope H100 instrumented indentation
tester equipped with Berkovich tip (tip radius ~200 nm).
The indenter induces stresses at the edges of the indentation
to create tension, which then leads to cracking and peeling of the PVD layer.
Over the decades, several test systems for gauging the hardness of materials have been introduced, such as scratch tests and indentation
For these coatings, conventional hardness measurement systems that rely on optical evaluation of the indentation
A 20 by 20 indentation
array with a spacing of 1.5 [micro]m between indentations
was employed to ensure that sufficient indents for each phase can be used in obtaining the average phase stress-strain curves.
