Non-Linear Multimode Response of Clamped Rectangular Plates to Acoustic Loading

Abstract

Acoustically induced fatigue failures in aircraft structural components have resulted in unacceptable maintenance and inspection burdens. In some cases, sonic fatigue failures have resulted in major structural redesigns. Therefore, accurate prediction methods are needed to determine the sonic fatigue life of structures. Many analytical and experimental programs to develop sonic fatigue design criteria, however, have repeatedly shown a poor camparison between analytical and measured maximum root-mean-square strain at high sound pressure levels. This paper presents an analytical solution technique for the large-amplitude random response of clamped rectangular plates considering multiple modes in the analysis.
