    In the central hole-drilling method, a rosette strain gage is mounted on a sample containing residual stresses. Then, using a drill, a small diameter hole with a depth slightly more than the diameter is located in the center of the strain gage. The strains are thus released around the hole area and measured by the three strain gages of the rosette.
