(54)System and method for testing a fillet bond


(57) A testing apparatus (600) for characterizing a tension strength of a fillet bond (128) of a test specimen (300) may include a lower fixture (634) and an upper fixture (602). The test specimen (300) may include a skin component (302) bonded to a stiffener component (308). The lower fixture (634) may maintain the stiffener component (308) in a fixed position. The upper fixture (602) may engage the skin component (308) at a pair of discrete engagement locations (626) on opposite sides of the fillet bond (128). The upper fixture (602) may be mechanically coupled to a gimbal joint (604) and may substantially isolate the filet bond (128) from asymmetric bending during application of a tension test load (500) to the fillet bond (128).
