0 Hz equivalent to indenter
rates between 18 nm/s to 18 [micro] m/s, respectively, were used.
6) Especially for deeper indentations, most of the stressed material underneath an indenter
tip is beyond its yield stress and can be expected to respond faster while the stress is still applied.
4] of penetration of indenter
3 in tested material 4.
First, the very brittle structure collapses around the indenter
and then starts to take up (absorb) fracture energy by the formation of radial cracks.
The ball indenter
provides an average hardness over an area of the surface.
The HRC value is calculated from the net increase in the penetration depth, as the force on the diamond indenter
is increased from the preliminary force to the total force and then returned to the preliminary force.
offers users of the Agilent Nano Indenter
G200 a comprehensive solution for mechanical properties mapping, while also delivering unprecedented testing speed.
Ductile surface wear is calculated by surface, affected by the indenter
, the difference between the areas before and after the impact of inventory :
Unfortunately, because of the size of the indenter
used and the high load applied, the data is very unreliable and has little to do with the actual surface affected by the peening process.
The tests were carried out on both specimens using diamond Rockwell indenter
with the tip radius of 200 [mu]m.
This kind of hardness of a loading-unloading indenter
cycle, cycle lasts 120 seconds, can cause a number of important mechanical properties, such as Martens hardness, elastic modulus, mechanical work of elastic deformation, mechanical work of plastic deformation, mechanical work of total deformation, tend to creep, tendency to hardening and the degree of hardening.
In a recent work, the authors have studied macroindentation of polymers by means of a flat cylindrical indenter
on high-density polyethylene (HDPE) and polyamide 66 (PA66) .
Due to the light load applied to the indenter
, test results from this instrument will not indicate the cold flow or creep characteristics of the material tested.
Cyclic ball indentation tests were performed using an electro-hydraulic testing machine equipped with a ball indenter
and two eddy current sensors (displacement resolution: 0.
penetration rate is set to a nominal indenter
velocity or loading rate.
