Deformation control in explosive forming History of explosive

History of explosive forming: • Applications mainly in 1960 -1980 • TNO research 1995

Energy Architecture Aerospace Different application areas

CAD die design and CAD/CAM die machining

Integrated shapes: nuclear RES pool CEA Cadarache-France

Extremely large shapes from thick plate: ITER

Test plate with Electron Beam weld A sector with double 60 mm thick wall

Many metals, also in welded condition: • aluminium alloys, also presipitation hardened • Stainless

Example of niche market with other explosion technologies
