Experimental studies using a bespoke Arcan test fixture characterise the structural performance of Linear Friction Welded (LFW) wing rib foot joints under combined tension and shear loading. Under tension dominated loading the LFW specimens demonstrated equivalent static strength to their integrally machined counterparts, but as loading becomes more shear dominated then LFW specimens demonstrate performance reductions. Residual strength tests on pre-damaged specimens however shows that LFW joints were more sensitive to tension dominated loading than shear dominated loading, with crack-opening fracture perpendicular to the weld line proving critical.
