The CU BW (CU Baden-Württemberg) cluster established the WG “Structural Integrity” in October 2014. The topics of crash, high velocity impact (HVI), damage tolerance (LVI), and residual strength are to be bundled in this WG. The sub-working group “Composite Fatigue” (until now affiliated to the WG Engineering) will bring its topics and activities with overlaps to the WG “Structural Integrity” into this working group and will be continued as a sub-working group.
