I want to understand the mechanism of fatigue failure of weld composites when the force applied is parallel to the welding direction.
Can anyone point out any research article?
This is because the granules (fibers) are not impeding the applied stress
Ameer K Ibraheem Yes, it's a weld of metal composite. I have seen many research articles that performed fatigue analysis on cross-weld samples but in my situation, the force is applied parallel to the welding direction.
"Fatigue Behaviour of Welded Composites: Influence of Process Parameters and Load Orientation" by E. Güneş et al., which investigates the effects of process parameters and load orientation on the fatigue behavior of welded composite materials. This study found that the fatigue strength of welded composites is sensitive to the load orientation, with the strength decreasing as the load orientation becomes more perpendicular to the welding direction. The study also found that the fatigue strength of welded composites is influenced by the welding process parameters, including the welding speed, heat input, and filler material used.
