ABSTRACT	ESDU 93027 discusses methods of testing structural elements, designed to represent features of the full-size structure, using random-amplitude narrow-band loading to simulate response to acoustic loading. A wide range of element geometries is included with information on probable failure locations, typical sizes, and any inherent limitations. Mounting methods are considered with examples of multiple specimen tests to allow the scatter in fatigue life to be determined in minimum elapsed time. Guidance is provided on excitation requirements, the measurement and monitoring instrumentation, specimen tuning, and the assessment of structural damping and response linearity. The means of defining a failure are considered, with particular reference to composite structures, and the use of residual strength assessment is discussed. The application of the techniques to obtain endurance data at elevated temperature is addressed. Finally, guidance is included on the interpretation of the results.
