Different contact surface parameters and operating characteristics are observed during the deep drawing process. It is not possible to find a formulation that can be used for all lubrication regimes. Therefore, several friction models have been developed in order to overcome this problem. In this study, a math program is developed which combines Wilson’s and Khonsari’s friction models in a new model in order to increase accuracy and efficiency in friction calculations. By comparing the results of both frict...
Computer aided modeling of deep-drawing

Deep-drawing operations are performed widely in industrial applications. It is very important for efficiency to achieve parts with no defects. in this work, a finite element method is developed to simulate deep-drawing operation including wrinkling. A four nodded five degree of freedom shell element is formulated. Isotropic elasto-plastic material model with Von Mises yield criterion is used. By using this shell element, the developed code can predict the bending behavior of workpiece besides membrane behav...
