Yielding and Fracture of Medium-Carbon Steel Under Combined Stress

Abstract

Abstract Results of combined stress tests on a medium-carbon steel are presented. Particular attention has been paid to the magnitude and the distribution of the stresses and strains at the instant preceding fracture. The effect of the shape of the test specimen and the isotropy of the material upon the rupture properties have also been investigated. This investigation was carried out at the Westinghouse Research Laboratories under a contract with the David Taylor Model Basin, Bureau of Ships, U. S. Navy Department, according to plans worked out by Captain W. P. Roop, U.S.N., of the David Taylor Model Basin, and Dr. A. Nadai of Westinghouse.
