    Abstract

    Many structures such as bridge decks and ship hulls are required to withstand fatigue load cycles throughout their service life. These structures are also required to withstand zero and subzero temperatures if located in northern and Arctic regions, where winter temperatures can drop down to −40°C. The combined effects of cold temperature and cyclic loads can lead to potential damage to the material performance and subsequent failure. In this study, CSA G40.21 350WT steel, which is typically used in ship building, was tested in strain-controlled fatigue load cycles to determine the effect of zero and subzero temperatures on the mechanical properties and fatigue life. The experimental results show a significant effect of temperature on the fatigue life of this steel. The tensile strength was not affected by low temperatures. The yield strength and fracture strength increased and the ductility decreased at low temperatures. This paper discusses the test procedure, test parameters, and test data obtained from this study.
