  • Damage tolerant design of the aircraft components
    Jelaska, Damir ...
    The integrity of high speed engine parts is particularly critical because the usually extremely high cyclic frequencies of in-service loading spectra cause that the fatigue life of e.g. ▫$10^7$▫ ... cycles can be reached in a few hours. That is why a number of fatigue failures has been detected in US fighter engines. It is therefore important to keep looking for a simple procedure enabling the designer a reliable estimation of crack initiation and propagation life for a given applied load, or to obtain the (boundary) load or (strain), at which the component would not experience the unpermissible damage during the designed life. The damage tolereant design refers to the design methodology in which fracture mechanics analyses predict the remaining life and quantify inspection intervals, a philosophy which allows the flaws to remain in the structure provided that they are well below the cristical size.
