Dynamic response of metals and alloys to laser-induced shock waves

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 shock 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.

Different Parts

The dynamic response of different parts of the chest wall of rabbits exposed to high-explosive shock waves has been recorded by means of a mechanoelectric motion transducer. The costal interspaces were found to be displaced inward with a greater amplitude and in a shorter time than the parts containing the ribs. The correlation of the "rib markings" in lung blast injury to these differences in amplitude are discussed.

A variety of materials containing many different microstructures have been examined with the USS MVEM. Three topics have been selected to illustrate some of the more recent studies of diffraction phenomena and defect, grain and multi-phase structures of metals and minerals.(1) Critical Voltage Effects in Metals and Alloys - This many-beam dynamical diffraction phenomenon, in which some Bragg resonances vanish at certain accelerating voltages, Vc, depends sensitively on the spacing of diffracting planes, Debye temperature θD and structure factors. Vc values can be measured to ± 0.5% in the HVEM ana used to obtain improved extinction distances and θD values appropriate to electron diffraction, as well as to probe local bonding effects and composition variations in alloys.
