Random errors caused by temperature in magnitude of principal strains evaluated ith 3‐element strain gauge rosettes
Paolo Cappa · Strain · 1989
The effects of the uncertainties associated ith the apparent strain and gauge factor data, given by the manufacturer, in the evaluation of principal strains are examined. Principal strains are obtained by a reduction of the strains measured ith electrical resistance strain gauge rectangular or delta rosettes. The theoretical analysis points out the relevance of the effects caused.
