Title: Study on the Hemisphere Deep Drawing Process of Metal Sheet Based on the FEM Simulation

Abstract

Deep drawing is a manner of the metal forming, and the most important position in the industry has been occupied because of its high efficiency. In the past, people often used a trial-and-error method and experiences to complete the deep drawing processes. However the time is consuming and the cost is high by this way, so this study adopts the finite element method to simulate the deep drawing forming in order to reduce the processing cost and time, furthermore to predict the thickness distribution of the product and to find the suitable forming parameters. The material properties and forming parameters have the significant influences to the deep drawing forming, such as strain hardening, plastic strain rate, friction and lubrication, blank holder force, radii of die and punch etc. In this study, two popular commercial FEA software, SUPERFORM and DEFORM, have been used to simulate hemisphere deep drawing forming, and the analysis results will be in comparison with experiment results published to verify the correctness of FEM simulations. Throughout this study, the effects of the blank holder force, the radii of die and punch, the gap between punch and die, the frictional coefficient etc upon the maximum forming force and themore » minimum thickness, are discussed systematically. After a series of simulations, the comparisons between the SUPERFORM and DEFORM show a good agreement with the experiment and the error is very small.« less

  • It is well known that the macroscopic anisotropy and formability of a sheet metal are significantly affected by the crystallographic texture. So it is very important to find texture evolution rule in metal forming processes. In this paper, a rate-independent polycrystalline plasticity model is developed and introduced into dynamic explicit element method. Metal flow is assumed to occur by crystallographic slip on given slip systems within each crystal. Every integration point is a single crystal. Then the stability of ideal orientations and texture evolution of polycrystal are investigated.
  • Lightweight design is essential for an economic and environmentally friendly vehicle. Aluminium sheet metal is well known for its ability to improve the strength to weight ratio of lightweight structures. One disadvantage of aluminium is that it is less formable than steel. Therefore complex part geometries can only be realized by expensive multi-step production processes. One method for overcoming this disadvantage is deep drawing at elevated temperatures. In this way the formability of aluminium sheet metal can be improved significantly, and the number of necessary production steps can thereby be reduced. This paper introduces deep drawing of aluminium sheet metalmore » at elevated temperatures, a corresponding simulation method, a characteristic process and its optimization. The temperature and strain rate dependent material properties of a 5xxx series alloy and their modelling are discussed. A three dimensional thermomechanically coupled finite element deep drawing simulation model and its validation are presented. Based on the validated simulation model an optimised process strategy regarding formability, time and cost is introduced.« less
  • In this study, we studied formability of PET/PVC laminated sheet metal which named VCM (Vinyl Coated Metal). VCM offers various patterns and good-looking metal steel used for appliances such as refrigerator and washing machine. But, this sheet has problems which are crack and peeling of film when the material is formed by deep drawing process. To predict the problems, we used finite element method and GTN (Gurson-Tvergaard-Needleman) damage model to represent damage of material. We divided the VCM into 3 layers (PET film, adhesive and steel added PVC) in finite element analysis model to express the crack and peeling phenomenon.more » The material properties of each layer are determined by reverse engineering based on tensile test result. Furthermore, we performed the simple rectangular deep drawing and simulated it. The simulation result shows good agreement with drawing experiment result in position, punch stroke of crack occurrence. Also, we studied the fracture mechanism of PET film on VCM by comparing the width direction strain of metal and PET film.« less
  • A new scheme for blank holding force (BHF) is introduced in order to apply more realistic BHF in simulation. The present study has been carried out for deep drawing processes of a washing-trough. Different blankholder gaps and separation forces simulate the blank holding process. The optimum blankholder gap and separation force are determined through a systematic approach. It is found that the wrinkling in the flange region of the blank increases with the augmentation of the blank holder gap. And the BHF increases owing to the elevation of the rigidity of the sheet metal. The simulated thickness with separation forcemore » is lower than that with the blankholder gap because the BHF is variable in the flange region. A comparison of the thickness and flange contour between the simulation results and experiment shows that the blankholder gap is better in the simulation of the BHF in sheet metal forming process.« less
  • Increasing use of new technologies in automotive and aircraft applications requires intensive research and developments on sheet metal forming processes. This study focuses on the assessment of sheet hydroforming, hydro-mechanical deep drawing and conventional deep-drawing processes by performing a systematic analysis by numerical simulations. Circular, elliptic, rectangular and square cross-section cups have been selected for the geometry spectrum. Within the range of each cross section, depth, drawing ratio and fillet radii have been altered systematically. St14 stainless steel has been used as the material throughout the study. The deformation behavior has been described by an elasto-plastic material model and allmore » numerical simulations have been carried out by using a dynamic-explicit commercial finite element code. During the analyses each workpiece is produced by the three competing processes. The analyses results such as sheet thickness distribution, necking, forming of radii etc., are used for assessing the success of each forming process alternative. The analyses revealed that depending on the workpiece geometry and dimensional properties certain processes are preferable for obtaining satisfactory products. The process windows for each process have been established based on the analyzed parameters of the three different product geometries. This data is expected to be useful for selecting the appropriate production process for a given workpiece geometry.« less
