Fatigue Behavior of AM-350 Stainless Steel and Titanium-8-A1-1Mo-1V Sheet at Room Temperature, 550 degree F and 800 degree F
Abstract
A series of fatigue tests were conducted on two candidate materials for use in a Mach 3 transport type aircraft. The basic materials and typical structural joining procedures were evaluated at temperatures to 800 F. Fatigue analyses were conducted in order to determine the suitability of these materials under the effects of variable amplitude loading at elevated temperatures. The need for designing aircraft for fatigue is well recognized and has become a part of any new aircraft development program. The advent of programs such as the supersonic transport where high speeds will be sustained for relatively long periods of time requires consideration of elevated temperatures in combination with repeated loading environments. This report presents basic fatigue aata on two candidate materials (Ti- tanium - 8Al-lMo-lV triplex annealed and AM-%5O CRT stainless steel) for a TTI%ch 311 transport aircraft and assesses the relative importance of fatigue loadings at elevated temperature on a vehicle of this type. This program was sponsored by the National Aeronautics and Space Admin- istration under Contract %Sw-%44. The ob%ectives were as follows:
