Abstract : Techniques are described which have been used to predict the possible effects of blast waves on ships' superstructures. The basic physical properties of a blast wave, the factors which affect these properties, and the techniques for measuring them are discussed. The interaction of schock waves with scaled rigid models is studied in the laboratory and the results are used to predict the blast loading on a full-scale structure. The dynamic response of the structure to this loading through the elastic, elasto-plastic, and plastic regimes can be calculated by reducing the structure to a system of simple single-degree-of-freedom components. These calculations are checked, when the opportunity arises, by studying the structure response on full-scale trials. (Author)
