Analysis and Test Verification of Lifting Lugs and Welded Joints
A structural unit is lifted via four standard deck plates. In doing so, the load path passes through a series of welded joints and structural members.
Verification of the mechanical integrity of the deck plates and welded joints was required for customer sign off.
Classical weld analysis and finite element analysis was carried out to evaluate the stress distributions under a gross “in-service” load of 6.5 tons.
A physical test was also conducted to verify analytical results.
