| Abstract | ||
| There are several approximate relations for the calculation of the strain energy of plastic deformation of an explosively formed part and the explosive energy received by the blank through the water as an energy transmitting medium. A new energy equation is derived by the author. The equations are evaluated using the experimental data of previous investigations. The best relations are obtained for a specified range of the LID ratio (stand-off distance/die diameter). The limitations of the validity of the relations are indicated. | ||
