Grahic Jump Location
Diagram of the two-piece FDT. The fillet designated “Point A” marks the failure location for all specimens loaded statically. The welded joint was the region of failure for the two median fatigue strength specimens that failed before 225,000 cycles.
Grahic Jump Location
Testing setup for the static and median fatigue strength tests. The FDT was threaded into the Delrin piece that was clamped in the aluminum fixture. The load applicator was attached to the load cell and moved by the hydraulic actuator. Loads were applied at the midpoint of the 10 mm FDT post.
