Deformation control in explosive forming History of explosive Slides: 23 Download presentation Deformation control in explosive forming History of explosive forming: • Applications mainly in 1960 -1980 • TNO research 1995 • Start Exploform 1998 • New, highly enhanced factory 2008 + Energy Architecture Aerospace Different application areas Smooth product surfaces CAD product design for production 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 Largest panel to be formed Many metals, also in welded condition: • aluminium alloys, also presipitation hardened • Stainless steels • Copper and copper alloys • Titanium alloys • Nickel alloys • Cobalt alloys • Composite materials • Powder Metallurgical materials • MIG, TIG, electrode welded • Laser welded • Friction Stir welded • Electron Beam welded • Explosion welded Simulations Simulations Example of niche market with other explosion technologies Forming Limit Curve ε 1 = 10% ε 1 10% ε 2= -5% Plane strain Bi-axial strain Free cross contraction -5% Strain paths Forming Limit Diagram ε 2 Photogrammetry deformation analysis Photogrammetry deformation analysis Photogrammetry deformation analysis Photogrammetry deformation analysis Thank you for your kind attention!
