Sažetak
In the thin-sheet metal shaping processes it is possible to use explosion energy for volume shaping as well as for other processes of thin-sheet metal shaping, like surface hardening, riveting calibration, sintering, casting under pressure, cast cleaning, mounting, etc. In the observed case there will be presented a process of determining dynamicity coefficient both based on existing theoretic equations for determination of required pressure, and based on experimental results of testing. As a matter of fact, a dynamicity coefficient is ratio between dynamic and static pressures and will be deduced from conditions of the equal deformation degree on the occasion of explosive-induced deep drawing of sphere-bottomed plate. In the observed case by means of explosion there was deeply drawn a sphere-bottomed plate with diameter 200 mm made of steel 4580. Explosive’ s detonation velocity was 2994 m/s and 6105 m/s. The explosive used was “ Vitezit 20” , while medium for energy transmission was water.
