The paper presents results of a preliminary study of the acoustic fatigue of an airframe structure as a result of turbojet engine noise. The acoustic pressure distribution, induced by jet-noise, is determined by a coupled FEM/BEM approach. A model of an airframe structure with no defects or microcracks is assumed to be subjected to loadings induced by a time-harmonic noise source. Solution techniques are summarized. A method is presented to analyze the acoustic stresses, additional to mechanical loading induced stresses, for the potential to initiate fatigue cracks and propagation of these cracks. Applications to similar structural systems are suggested.
