The Shape of the Neck and the Fracture of Tension Specimens

Abstract

The tensile test has been used, and is still being used, as the standard test for investigating the plastic properties of metals. The interpretation of the data taken beyond necking has been somewhat ambiguous due to the presence of transverse stresses of unknown magnitude. Professor Bridgman has removed this ambiguity by the calculation, presented in this report, of the three dimensional stress system in the neck of a tensile specimen. He also presents further observations upon the nature of and the conditions for fracture.
