..., the chapter considers two cases. In one, the relationship between strain range and cyclic life is established from test data. In the other, a rule is required to determine the damage of each concurrent strain and the total damage of the cycle is used to predict creep-fatigue life. The chapter presents several...

... at temperatures well below their creep and oxidation regime ( Ref 12.33 ). The ceramic fibers thus can be considered to respond elastically. They fracture in a brittle fashion when a maximum critical tensile strain (or stress) is reached. Hence, only the metallic matrix undergoes fatigue in the classical sense...
