SONIC FATIGUE IN COMBINED ENVIROMENT

Abstract

Research on sonic fatigue in combined environment is described. Emphasis is placed on determining the effects of structural curvature, low- frequency vibratory loads, and heat, both singly and collectively, on sonic fatigue. The analytical and experimental investigation is presented in two major phases: (1) An investigation of simple structural panels to determine the effect of curvature and heat cycling schemes on dynamic response and fatigue. (2) An investigation to determine the effects of high-intensity sound, heat, and low-frequency vibratory loads on curved titanium-faced honeycomb sandwich panels.
