Fatigue life prediction. Notion of endurance curve
Fatigue of continuous fiber reinforced composite materials

The growing use of high-performance composite materials is undoubtedly due to their exceptional fatigue resistance. Even lighter than aluminum alloys, they are significantly better than the latter when subjected to cyclic loads.

As a criterion, we usually evaluate the ratio σ _D /R _m of the endurance limit (or fatigue limit) σ _D to the tensile strengthR _m .

The most widely used criterion for assessing...
