Relevant Errors Associated with Tension Testing of Metals
The problems of properly evaluating the tensile properties of metals are examined. In particular, we estimate the errors introduced by the use of simplified relationships that do not consider the change in specimen volume during the test, and by ordinary regression analysis performed with only one uncertainty-affected variable. Typical values of these errors on different materials are computed by means of tension tests on cylindrical specimens.
