Notes:
There is no simple linear relationship between strain and potential in strain measurementwith strain gauges, especially for large strain measurements. In this paper, a modified algorithm wasproposed to improve the accuracy of strain obtained from measured voltage. The strain wascalculated from a nonlinear relationship between voltage and strain rather than a linear simplification.Moreover, the corrections for different sensitivity factors of strain gauges and lead wire resistancewere considered. The proposed method was suitable for both large and small strain measurementsusing a quarter bridge, and validated by experimental tests. It is also very easy to be implemented as asoftware form and used in scientific tests and engineering applications
