چکیده مقاله:
This paper presents a new methodology for complete solution of general shape deep drawn parts. Evaluation of forming severity, estimation of the punch load and prediction of the thickness variation are the major results obtained in this work. The punch work is the summation of the homogenous work of flange deformation and bending and frictional works. To evaluate the strain energy of the flange, the so-called matrix method of slip line is used. To overcome the weakness of slip line field in prediction of the thickness variation, the so-called genetic algorithm has been adopted. In this procedure, the actual velocity field has been computed and used in energy formulation. The predicted thickness strain, punch load and forming severity have been compared with some published experimental results.
