Fatigue Behavior of Aluminum and Titanium Sheet Materials Down to -423°F
Because of the behavior of structural materials at low temperatures, selection of the proper materials for booster and space vehicle systems which use cryogenic propellants is a challenge. Routine mechanical properties, such as tensile and compressive strength, modulus of elasticity, and ductility, are usually determined to assess the behavior of a candidate material. Behavior under stress concentration and cyclic loading conditions must also be studied to evaluate adequately a potential material.
