The NUMISHEET conference series is the most significant international conference on the area of the numerical simulation of sheet metal forming processes. It gathers the most prominent experts in numerical methods in sheet forming processes and is an outstanding forum for the exchange of ideas and for the discussion of technologies related to sheet metal forming processes.

Topics covered in this volume include but are not limited to the following:

• Materials Modeling and Experimental Testing Methods
• Friction and Contact
• Formability, Necking, and Fracture
• Instabilities and Surface Defects
• Fracture and Damage
• Numerical Methods
• Springback
• Incremental Sheet Forming
• Roll Forming
• Innovative Forming Methods
• Product and Process Design and Optimization
