The truss mounts attach the aircraft engines to the wing structure. The study required nonlinear FE analysis techniques due to the yielding behavior of the metal and the transfer of bearing loads through contact of the various components.C-130 Truss Mount Lug Structural AnalysisC-130 Truss Mount Lug Structural Analysis
