An enhanced unfolding Inverse Finite Element Method (IFEM) has been used together with an extended strain-based forming limit diagram (EFLD) to develop a fast and reliable approach to predict the feasibility of the deep drawing process of a part and determining where the failure or defects can occur. In the developed unfolding IFEM, the meshed part is properly fold out on the flat sheet and tre...

The effects of input parameters on the square-cup deep-drawing process for a two-layer aluminum/steel laminated sheet were investigated. Each layer was 0.7 mm thick, and the input parameters covered in the investigation were punch nose radius (PR), die shoulder radius (DR), the clearance between a punch and die (CPD), blank holder force (BHF), and layer arrangement (LA). The effects of the inpu...

The main objective of this research is to identify optimal printing strategies and PLA (polylactic acid) filament materials produce rapid prototype deep drawing tools. Additive 3D technologies have been applied for a long time tools, but the unique in that it uses conventional various reinforced with FDM (Fused Deposition Modeling) printers. advantage method easy print recycle does not require ...

In this work, thermal deep drawing and thermoelectric coupling tests were performed on an annealed ZK60 magnesium alloy sheet to investigate the effect of pulse current formability during process. The effects forming drawn parts studied, changes thinning rate hardness obtained. results showed that using improved increased ultimate depth drawing. value part overall increasing trend, followed by ...

The introduction on large scale of high strength materials in automotive industry provided the possibility to reduce weight and produce safer cars. But at the same time these materials yield more springback than deep drawing steels. This can lead to problems designing the right tools for the forming process. This paper presents a method for the optimization of sheet metal forming parameters in ...
