JANOSCH ABSTRACT.

Is it time consuming to design fillet weld joints?Is it time consuming to design fillet weld joints?In view of the range of weld details to be considered in design, and the inevitable variation in local geometry (weld toe angle and radius), this would be too time consuming for most design situations.Fatigue Design Recommendations for Fillet Weld Joints - TWI When to use fatigue design for welded joints?When to use fatigue design for welded joints?It is only relatively recently that a significant database from fatigue tests on welded joints under non-proportional loading, when the principal stress direction changes during a load cycle, has become available [4-6,9,13] . Consequently, current fatigue design methods are based more on judgement than experimental evidence.Fatigue Design Recommendations for Fillet Weld Joints - TWI10.1016/S0142-1123(97)87117-4 DeepDyve
