Özet

In practice, the problems connected with the fatigue of composites are intricate because of their complex structure and the fatigue loading. Fatigue tests under different fiber orientation angles are time-consuming and also very expensive. Therefore, it is important to establish a technique to consider the fatigue damage at any fiber orientation angle without having to perform excessive amounts of testing. The general purpose is to elaborate a methodology for finding a globally optimum design of composite laminates subjected to in-plane loads. In this part of the study, the Fawaz-Ellyin model of fatigue life prediction is presented and further validated. The results obtained show that the model can be applied to optimization problems of composites.
