Fatigue Analysis of Welded Structures Finite Element Analysis of Durability and Fatigue Life: Vibration Fatigue, Creep, Welded Structures Fatigue, Elastomer and Composite Fatigue

It is crucial to evaluate the fatigue behavior of welded joints as they are often critical components in various engineering applications such as automotive, aerospace, and structural engineering. Welded joints are subjected to complex loading conditions that can cause fatigue failure over time. Therefore, it is essential to use advanced numerical simulation software and methods to simulate the welding behavior and estimate its life under real-service load conditions.

Simulation Dynamics uses various fatigue analysis tools such as Ansys Ncode, Simulia FE-Safe, and FEMFAT to perform fatigue simulations on welded joints. These software packages allow for detailed modeling of welded joints and can simulate various types of welding such as fillet, overlap, spot welds in thin sheets, and laser welded joints.

By using advanced numerical simulation software and methods, the fatigue life of welded joints can be accurately estimated, and critical locations and load combinations can be identified. This allows for the optimization of the welding design and material selection to improve the durability and reliability of the welded joint in real-service load conditions.
