Round Thin Diameter Specimens
Specimen Preparation
Round Thin Diameter Specimens
A typical gaged specimen has three levels of strain gages. The gages allow you to
determine bending strains at each level. Analysis of the strain readings produce a
profile of the grip alignment.
Gage placement On small diameter specimens where you cannot use four gages at each level, use
three gages at each level. Attach and number the nine gages as shown here.
Gage Placement—Three Gage Round Specimens
• Place the gages at the top, middle, and bottom of the gage section. Space
them at 120° 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 bottom
of the gage section.
