Abstract

It involves the fatigue behavior of K-Joint made of HSLA material using numerical analysis. Use of High Strength Steel instead of using normal grade steel makes the structure lighter and increases the strengths. The fatigue crack growth initiation is always observes at the chord crown toe location irrespective of the stress whether compressive or tensile. Stress distribution plays an important role in the geometry of K-Joint under fatigue stress. As observed, location around the weld has the highest hotspot stress are highest still chord crown toe are at most critical fatigue risk, hence stress investigation have to be performed. The stress in the region surrounding the weld is computed using numerical simulation and the component with the highest residual stresses are discussed.
