Description

The aim of this note is to reveal the mechanism of the cause of strain measurement errors measured by strain gauges placed on a curved surface. It has already been reported that there appear some measurement errors in the values of tangential strain measured on a cylindrical specimen. In this note, the cause of measurement errors in strain gauge measurements is discussed theoretically, and the mathematical equations expressing a relationship between the measured and real values of tangential strains in a cylindrical specimen are derived. The adequacy of the equations are verified by analyzing the experimental results obtained in the laboratory tests. Although the discussion is given only on the case of cylindrical specimens, it is possible to extend these equations to a specimen with concave surface.
