This important, comprehensive book examines and explains advanced methods and skillsa€”including circle grid analysis and finite element analysisa€”to enhance formability measurement and analysis. Its technical foundation includes metallurgy, engineering mechanics (plasticity) and forming die surface and die component kinematics. It also studies broad stamping defects that are affected multiple variables in stamping engineering and production. The author has amassed more than 10 years of stamping experience at Ford Motor Company as a draw die specialist, project leader, stamping CAE analyst and stamping process engineer. His responsibilities at Ford have included the establishment and management of a formability lab, improvement of die performance in stamping production, draw die development, problem solving during die tryouts and launch, sheet metal performance control, stamping engineering tool development and stamping CAE. Throughout the book, emphasis is on defects severity measurement and analysis versus stamping variables, and special features include deformation characterization of stampings; structuralization of deformation fields; measurement of formability indexes; establishment of stamping process windows; and applications of the control principles of metal flow technology. Applications for the automobile industry are highlighted throughout, and are featured in a chapter dedicated to the subject.[122] Livermore Software Technology Corporation, LS-DYNA Usera#39;s Manual, Version 960, 2001 .
