Abstract:

Presents background, test results and test Setup for the DC-9 aft pressure bulkhead residual strength test. The tests were intended to validate the analytic methods of determining widespread fatigue damage WFD and multiple site damage MSD effects on the residual strength of a complex aft pressure bulkhead structure. Strain data was taken from a variety of locations on the bulkhead pressure web, and from this data, the following information about the aft pressure bulkhead was derived residual strength stress distribution around the lead crack growth rate of the lead crack stress level at link-up of the crack between fastener holes
