    Abstract
  • Acoustic fatigue of composite structures concerns many researchers. Numerical simulation is often used to deals with this problem. In this paper, BEM is used to simulate the dynamic response of composite structures, and a numerical simulation method of acoustic fatigue of composite structures is presented. The results can provide references for forecasting acoustic fatigue life of composite structures.
