Abstract : Fatigue properties were evaluated for sandwich constructions of titanium and nickel-base alloys having facings resistance-welded to honeycomb cores. Cores were of corrugated foil formed to 1/4-inch-squared honeycomb cells. Flatwise tension and flatwise shear properties were evaluated at 75F. for three constructions of each type. Edgewise compression fatigue properties were evaluated for two constructions of each type. Endurance limits of the sandwich tested were about 10 to 13 percent of static strength in flatwise tension, 10 to 20 percent in flatwise shear, and 40 to 70 percent in edgewise compression. (Author)
