Slide 2
The sample geometry
is a circular cylinder with a reduced diameter gauge section as
seen at the bottom of this slide. At the ends there is a 25.4mm
diameter grip region for holding the samples in our hydraulic collet
grips. Some of the samples are hollow cylinders and some are solid.
All of the samples start as solid cylinders a few mm larger than
the final grip region diameter of 25.4mm. The cylinders are first
cut down to 25.4mm (one inch) outer diameter. For the hollow samples,
a hole is then drilled. This hole is then reamed to the precise
inner diameter. Once the hole is cut, the cylinder is machined to
produce the reduced diameter gauge section and fillet.
