Analysis of Deep Drawing Process for Stainless Steel Micro-Channel Array
The stainless steel bipolar plate has received much attention due to the cost of graphite bipolar plates. Since the micro-channel of bipolar plates plays the role of fuel flow field, electric connector and fuel sealing, an investigation of the deep drawing process for stainless steel micro-channel arrays is reported in this work. The updated Lagrangian formulation, degenerated shell finite elem...
متن کاملNumerical Determination of the Forming Limit Diagram for 304 Stainless Steel Based on Phase Change in Deep Drawing Process
Up to now a large number of models have been developed to measure or predict the damage in equipments. Some of these models have been implemented in ABAQUS software. To implement damage parameters in the software, it is necessary to perform complex and expensive practical tests. One of these damage models is Forming Limit Diagram (FLD).The purpose of this research is deriving required parameter...
متن کاملMicro-macro analysis of steel sheet behaviour in finite element simulations. Application to deep-drawing process
This paper presents a constitutive law based on Taylor’s model implemented in our non-linear finite element code LAGAMINE. The yield locus is only locally described and a particular interpolation method has been developed. This local yield locus model uses a discrete representation of the material’s texture. The interpolation method is presented and a deep-drawing application is simulated in or...
متن کاملEffect of Thickness to Grain Size Ratio on Drawability for Micro Deep Drawing of AISI 304 Stainless Steel
Although deep drawing process in the macro scale are well developed, the known concepts cannot be applied to micro deep drawing through directly scale down the specimen and tooling size due to the so-called size effects. Therefore, tensile test and micro deep drawing experiments were conducted to generate the knowledge for the micro deep drawing process. Stainless steel 304 foils with 4 differe...
متن کاملAnalysis of Stainless Steel Bipolar Plates Micro-Stamping Processes
Bipolar plate is one of the key components of proton exchange membrane fuel cells (PEMFC). Since the production costs of traditional graphite bipolar plates are very expensive and need a few millimeters thickness over the space, the resulting metal bipolar plate not only reduces the cost of such a bipolar plate, the thickness can also be reduced to micron range. This study aims to explore the a...
