cruciform joint

Cruciform joints suffer fatigue when subjected to continuously varying loads.

A cruciform joint is a specific joint in which 4 spaces are created by the welding of 3 plates of metal at right angles.

Finite element analyses of the cruciform joints indicated that the presence of a weak zone in the load path tended to concentrate strain in this zone and to initiate failure there.

In the American Bureau of Shipping Rules for Steel Vessels, cruciform joints may be considered a double barrier if the two substances requiring a double barrier are in opposite corners diagonally.
