Computer-aided deformation analysis of deep-drawing process

Modelling and simulation of friction in deep drawing Başpınar, Murat; Akkök, Metin; Department of Mechanical Engineering (2011) 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 Piskin, Mehmet Ali; Kaftanoglu, Bilgin (2007-04-04) 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...

Analysis of wrinkling in deep drawing processes Dal, Saniye Rabia; Darendeliler, Haluk; Department of Mechanical Engineering (2019) Wrinkling, observed due to compressive instability, is one of the main failure modes in deep drawing processes. The prediction and prevention of wrinkles are critical for production of stamping parts which require good surface quality. In the current work, the occurrence of wrinkling in square and cylindrical cup deep drawing processes are investigated considering various constitutive models; formed by using CPB06ex2, Hill’48, BBC2008-8p, BBC2008-16p, and von Mises yield criterion with isotropic, kinematic ...
