A study was made on underwater shock waves produced by exploding wires. Detail on exerimental equipment and procedure are given for both circuit and pressure measurements. The influence of capacitance, inductance and gap length on maxmum shock pressure P sub m is discussed. Experimental results correlating initial capacitor voltage between 10 and 30 kv with P sub m are given. An increase of voltage and gap length along with a decrease in inductance all tend to incease P sub m. By using the empirical P sub m vs voltage curve and extrapolating to zero P sub m, a voltage is obtained which corresponds closely to wire sublimation energy. Reproducibility, expressed quantitatively by standard deviation is within 2 percent. The ease of P sub m variation, along with reproducibility, indicate the suitabilty of this method of shock formation as a research tool.
