| Popis: | The explosive forming of steel blanks into a perforated square die of side 200 mm and depth 40 mm has been investigated. The results show that blanks can be successfully formed with perforated dies and that the smaller the percentage of perforation and vent size, the greater the quantity of explosive needed for successful forming. The results also show that the indentation of deformed blanks at the vents is more prominent when large sized vents are used, and decreases with increase in standoff distance. The results also show that better die filling at the corners of the die is obtained if more vents are provided at the corners of the die. |
