Static and cyclic strength of a uniaxially reinforced material in bending (part 1)

A built-up degree of damage μ=Δf/fo ≤8% has virtually no effect on the static strength of an AD33-B CM operating in air. The arbitrary fatigue limit corresponding to this volume of damage on a basis of 2–105 cycles may be taken to be equal to (0.5–0.55) σt. Accelerated buildup of damage on a basis of 2–105 cycles is observed at σa > (0.5–0.55) σt.
