Notched Flat Thick Specimens
Specimen Preparation
Notched Flat Thick Specimens
A typical 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 thick flat specimens. Attach and number them as shown here.
Gage Placement—Notched Thick Flat Specimens
• Place the gages in sets of four, at the top and bottom of the gage section.
Center each gage between the edges of the specimen.
• Place the top set of gages so that their upper edges just touch the upper edge
of the gage section.
• Place the bottom set of gages so that their lower edges just touch the lower
edge of the gage section.
