Stress and strain measurements in static tensile tests
Metrology and Measurement Systems, 2012 Abstract The paper deals with the accuracy of measurements of strains (elongation and necking) and stresses (tensile strength) in static room-temperature tensile strength tests. We present methods for calculating measurement errors and uncertainties, and discuss the determination of the limiting errors of the quantities measured for circular and ...
