Notched Round Thick Diameter Specimens
A typical notched gaged specimen has two levels of strain gages. The gages
allow you to determine bending strains at each level. Analysis of the strain
readings produces a profile of the grip alignment.
Gage placement
Use eight gages on large diameter round specimens. Attach and number them as
shown here.
Gage Placement—Notched Four Gage Round Specimens
• Place the gages at the top, middle, and bottom of the gage section. Space
them at 90° intervals.
• Place the top set of gages so that their upper edges just touch the upper edge
of the gage section.
• Center the middle gages in the middle of the gage section.
• Place the bottom set of gages so that their lower edges just touch the lower
edge of the gage section.
