The system for sheet metal forming design of complex parts

摘要: Abstract In the paper system for sheet metal forming design is described. The incorporates into finite element method limit stress diagrams and wrinkling criterion, as conditions of constitutive equations boundary describing materials reaction on complex deformation conditions. Application creates possibility to processes without expensive time consuming trail error techniques, so that necessity investigation by using real tools may be reduced or eliminated. will able predict loads, create geometry tools, calculate distribution strain determine process condition.
