Abstract

Experimental evaluation of calibration constants using a specially designed indigenous strain gage rosette is presented. Performance of this indigenous rosette is compared with an imported rosette and theoretical results. The calibration constants can be used for the determination of residual stresses in structural components by the hole drilling technique.

Keywords:
residual stresses, hole drilling technique, calibration constants, strain gage rosette
