The analysis for the impulse delivered to a blank using a modified Taylor analysis was programmed in Fortran IV language and compiled. The next quarters effort will be devoted to checking out the program and comparing theoretical results with experimental measurements. An improved technique for bonding strain gages was developed which provides strain measurements on explosively deformed blanks up to 5.5. Initial experimental work was initiated on the energy delivered to dies. Additional results on strain rate effects is reported. The preliminary work on explosive forming and punching of armor was started. The safety system for the capacitor bank has been installed and is operational. Preliminary results on the effect of explosive forming on stress corrosion cracking, terminal materials properties, and recovery and recrystallization are reported. Recent results on the mechanics of energy transfer and high velocity metal deformation are reported.
