Symposium Formability and Fracture of Metal Sheets
Organizer(s) Piyush Upadhyay, Pacific Northwest National Laboratory
John E. Carsley, General Motors Company
Daniel R. Coughlin, Los Alamos National Laboratory
Kester D. Clarke, Colorado School of Mines
Scope The fabrication of complex shapes from ferrous and non-ferrous sheet metal is important for a broad range of industries, including aerospace and automotive, and requires understanding of material behavior across a wide variety of strain states, paths, and rates. The main objective of this symposium is to provide a high-level scientific forum that spotlights the numerous advances in the experimental and computational methods used for constitutive analyses and improves our knowledge of the mechanical and metallurgical responses of metal sheets in complex sheet forming processes. This includes increasing our understanding of the relationships between complex microstructures and mechanical behavior, as well as the relative influences of strain path and temperature on formability and failure. Topics of interest include:

• Experiments and modeling related to formability and fracture
• Novel forming processes
• Advanced characterization methods
• Multiaxial deformation
• Deformation induced phase transformations
• Friction and springback
• Microstructure development for formability
• Constitutive relationships
• Multi-scale mechanical testing
