| Abstract: | A further research on the extension behaviour of fatigue cracks by a biaxial tension is dealt with based on the report "An Investigation into the Welded Joint Fatigue of a Thin-walled Pressure Container", putting emphasis on the exploration of mechanism of the creation, and the extension direction of fatigue crack extension, as well as on the factors which affect the fatigue crack extension. |
