Abstract : A literature survey in capacitor discharge extrusion and dynamic effects of shock loading was completed. A stress analysis considering the effect of explosive shock type loadings is nearing completion. The objective of the program is to extrude steel to 1/4 in. rounds by the use of capacitor discharge energy. Pressure chamber requirement is a vessel which must hold hydrostatic pressure of 200,000 psi and be capable of containing shock energy from a 155,000 joule capacitor discharge.
