AIRPLANE STRUCTURE FATIGUE TESTING METHODS

Abstract

The presented article deals with the fatigue testing of aircraft structures. The fatigue process has certain stages, his character is cumulative and irreversible. The most important data about the fatigue resistance of structures can be obtained only by fatigue tests. Fatigue tests are performed on samples, models and entire structures. The aim in the fatigue test is simulate an operation loading. The selected method of the loading affects the credibility of the results. Applying all knowledge is implemented in the draft program loading of the fatigue test. In this draft are described the basic procedures that are part of each fatigue test aircraft structures
