The Effects Of Variations In The Excitation Parameters Of Blast Waves On The High Frequency Response Of Circular Rings, Paul John Mirabella
The Effects Of Variations In The Excitation Parameters Of Blast Waves On The High Frequency Response Of Circular Rings, Paul John Mirabella
Retrospective Theses and Dissertations
The high frequency response of a circular ring of rectangular cross section interior to a conical shell excited by a blast wave is examined. The ring supports a rigidly attached mass during excitation. It is hypothesized that the response is a function of the four excitation parameters which characterize the loading. These are: peak reflected pressure; characteristic time (pulse duration); wave engulfment time; and circumferential distribution. These parameters are varied over a range of interest in an effort to ascertain the structural sensitivity to such perturbations. A series of tests sponsored by the Department of the Army and the Martin …
