Working Group 5

Compound Problems

WG5 lays the groundwork for future benchmarking in complex engineering problems. Building on WG4, it explores additive manufacturing, fatigue in contacts, welded joints, and riveted joints, where multiple effects interact. While no benchmark sets are expected, findings will guide future research, including post-FABER projects.​

W.G.5.1

Additive Manufacturing​
This task examines challenges in additive manufacturing, including porosity, residual stresses and complex geometries of built surface conditions. It explores size effects, notch sensitivity, multiaxial loading, and surface quality. The goal is to enhance the reliability of AM-produced components.​

W.G.5.2

Fatigue in Contacts​
Fatigue accelerates when contacting parts, like rivets and bolts, experience relative movement. Stress gradients and multiaxial stress states complicate predictions. This task improves fatigue assessment for contact interfaces to enhance durability.​

W.G.5.3

Welded Joints​
Welding introduces residual stresses, particularly in the heat-affected zone. This task studies their interaction with mechanical loading to ensure welded structures’ integrity. Insights apply across industries like aerospace and construction.​

W.G.5.4

Riveted Joints​

Riveting is common in aerospace, automotive, and structural engineering but poses inspection challenges due to hidden cracks. This task investigates durability and failure mechanisms to improve riveted joint reliability.

Activities

WG5 will collaborate with WG4 to refine benchmark methods, organize technical workshops on compound fatigue challenges, and establish long-term partnerships with industrial partners.

Deliverables

WG5 will generate survey papers on experimental fatigue data, provide technical guidelines for compound problem benchmarking, and propose new standards for fatigue testing in complex structures.
