Fatigue in Welded Structures
What will you learn?
This training course is aimed at those who have knowledge of structural mechanics and of the finite element method and want to learn how to evaluate welded connections with respect to static strength and fatigue life using the Finite Element Method (FEM).
- General understanding of the methods for analyzing static strength of welded connections.
- Introduction to general fatigue and learn the terminology and using ANSYS Fatigue Module.
- Get the basic understanding of the most common weld fatigue methods according to Eurocode 3, International Institute of Welding (IIW) and DNV RP C-203.
- Implementation and usage of weld fatigue best practice methods for solid and shell elements.
- The training is updated with respect to the IIW recommendations and the EDRMedeso apps: “Weld Strength” and “Weld Fatigue”.
