They further said mostly indentors deals in basic raw material of Industries and they are source of quality goods supplying to manufacturing and Export sector to ensure smooth production of industries .
They requested to Chief Minister of Sindh, Provincial Finance Minister and Chairman SRB to consider their One point demand and exempted Indentors services from Service Tax.
The subject panel is used for recording the subject's pressure perceptions related to discomfort and pain [29,31] and as a safety device: when the pain switch is pressed, the indentor is released automatically.
To support rate-controlled indentation, we used a cylindrical indentor with a load cell driven by a stepper motor, allowing indentation rate variations from 0 to 10 mm/s, which is appropriate for tissue [13,23].
23) reported that for PMMA, depending on the shape of a conical indentor (various values of cone included angle and tip radius), the critical load could increase with the scratch speed, or it could decrease.
In addition, to better understand the effect of the contact size and geometry on the scratch mechanisms, recent finite element simulations have allowed for the computation of the distribution of the stresses and strains around the contact, and highlighted the evolution of these stresses with the size and geometry of the contact (in particular, the included angle of the indentor and tip radius).
The difference in these hardness results was due to the difference in indentor geometry for these hardness tests.
However, it has been found that the indentor geometry has direct influence on the type of damage mode during scratching (1).
The new approach is to progressively load the indentor with comparatively small loads and to measure the indentor penetration depth with the indentor in place.
Hardness (micro and nano hardness) at different depths is therefore simply measured and the indentor can be set to measure depths from around 1[mu]m up to tens of micrometres depending upon material hardness.
For example, in an early account of pressure flaking, Clement (1903:5) confused how the indentor
was held and used.
There is a significant difference in torsional resistance created by the different shapes of the indentors
