Uncertainty associated with the gage factor in three-element strain-gage-rosette measurements

Research output: Contribution to journal › Article

Abstract

The uncertainty associated with the gage factor in the evaluation of principal strains is examined. Principal strains are measured with electrical-resistance strain-gage rectangular and delta rosettes. The theoretical examination points out that, in the worst case, the effect of gage-factor uncertainty is not negligible and, in some conditions, is significant. These results have been confirmed by experimental analysis.
