Computer-aided testing and modal analysis; Proceedings of the Fall Conference, Milwaukee, WI, November 4-7, 1984
Aspects of dynamic measurements and modal analysis are discussed, taking into account the single-degree-of-freedom model and the two degree-of-freedom model for the elementary vibration response, the dynamic response of material in vibrations, elementary digital frequency analysis, the use of the microphone and impact hammer windowing in modal testing, and a dynamic analysis of a rotating anode x-ray vacuum tube. Other subjects studied are related to experimental measurements, computer strain-gage data acquisition and analysis, structural analysis and testing, automated fatigue in testing, composites, transducers, automatic fracture-mechanic testing, and nondestructive testing. Attention is given to ultrasonic crack characterization by the time-domain Kirchoff approximation, a direct comparison of unloading compliance and potential drop techniques in J-integral testing, computer-aided dynamic testing of composite materials, fatigue and mean stress, an evaluation procedure for raw fatigue data, and a buckling test of a micro-concrete model of a folded plate shell.
