Series 609 Alignment Fixture Product Information Specimen Preparation

Notched Thin Flat Specimens

A 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 thin flat specimens. Attach and number them as shown here.

Gage Placement—Notched Thin Flat

• On thin rectangular specimens where gages cannot be attached to all four

sides, use this eight gage front-to-back arrangement. Attach and number the

gages as shown here.

• Place the gages in sets of four, at the top and bottom of the gage section.

Place each gage as close as practical to the edge of the specimen. Keep the

distance from the edge the same for all gages. Measure the distance from the

edge of the specimen to the middle of the gage. This distance will be used in

your bending strain calculations.

• 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.
