Sonic fatigue is generally considered as being one of the major design areas for the newest generation of high-speed flight vehicles. Efficient analysis methods for predicting nonlinear random response and fatigue life are urgently needed. This paper

Acoustic fatigue in aircraft is typically characterized by random, high-frequency excitation that results in fully reversed bending in panels. Because of the expense of testing panels in an acoustic environment, traditional methods have first tested

A methodology is presented that predicts the fluctuating pressure and power spectra for attached zeropressure gradient and separated turbulent boundary-layer flow on smooth and rough surfaces. Attached flow conditions use a prediction technique that

In stochastic structural dynamics, majority of the analyses have dealt with linear structures under stationary Gaussian and band-limited white-noise excitation (WN). Recorded B-1B flight acoustic pressure fluctuations have shown: (i) the high levels

Acoustic excitation produced by jet-engine effluxes was simulated in a progressive wave tube (APWT) facility with a computer-based control system. The APWT siren is driven by a signal generated numerically in a PC and then converted into analog form.

High sigma events were studied in the narrowband random response of a cantilevered beam excited by an electrodynamic shaker. The effects of truncating the input signal to the shaker with a Blackglas beam are discussed. Tests were conducted with the s

The penetrant-carrier capacity of dimethylsulfoxide (DMSO) through intact human skin was studied with allergens of varying molecular sizes and compositions. Results showed that only with DMSO 90 per cent and penicillin could positive Prausnitz-Kustne

This paper presents a discussion of analytical and experimental techniques to predict the acoustic fatigue life of aircraft structures. A brief discussion of the problem and current steps taken to solve the problem are given. A brief review of analyt
