Development of an analytical model for warm deep drawing of aluminum alloys

Journal of Materials Processing Technology, 2008
In this study, an analytical model was developed to investigate the effects of material, process, and geometric parameters in the warm forming of aluminum alloys under simple cylindrical deep drawing conditions. The model was validated with both existing experimental findings in the literature and FEA results. The effects of the main process parameters

Deep-drawing of magnesium alloy sheets at warm temperatures

Journal of Materials Processing Technology, 2007
Abstract In magnesium alloy sheet products have been attracting more and more attention in recent years because of their application potentials as coverings of portable electrical devices and automotive panels. However, magnesium alloy sheets are usually formed at temperatures between 250 and 400 °C because of their poor plasticity at room ...

Comparative study of warm and hydromechanical deep drawing for low-carbon steel

International Journal of Advanced Manufacturing Technology, 2015
Deep drawing is a process of converting sheets into cup-like-shaped components. It is a complex process, and process parameters play an important role. In this paper, two deep drawing processes namely warm deep drawing and hydromechanical deep drawing are compared. A 20-t hydraulic press is used to draw the cups.

Numerical simulation on warm deep drawing of magnesium alloy AZ31 sheets

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2009
Warm forming of magnesium alloys has attracted much attention due to the very poor formability of Mg alloys at room temperature. In the present paper, the warm deep drawing of magnesium alloy AZ31 (3 wt.% Al, 1 wt.% Zn) sheets was studied by both the experimental approach and the finite element analysis.

Numerical and experimental investigations on the Warm Deep Drawing process of circular aluminum alloy specimens

Journal of Materials Processing Technology, 2007
Abstract Warm Deep Drawing process of circular 0.8 mm thick specimens in AA5754-O was investigated using a home designed experimental equipment and a finite element fully coupled thermo-mechanical model. The research activity was aimed to investigate the formability (evaluated by means of the material Limit Drawing Ratio) of the AA5754-O by means of ...

A study on the analytical modeling for warm hydro-mechanical deep drawing of lightweight materials

International Journal of Machine Tools and Manufacture, 2007
The warm hydroforming process has become an emerging technology in recent years to reduce the weight of automotive body structure and minimize the number of process steps. In this study, analytical models were developed to investigate the effects of process conditions such as temperature, hydraulic pressure, blank holder force and forming speed.

Investigation on Formability of AISI 304 Circular Cups by Warm Deep Drawing

Advanced Materials Research, 2011
Deep drawing is one of the sheet metal forming processes used widely in industries like automobile, aerospace etc. In drawing operation, the limiting draw ratio (LDR) is used as an index of drawability of a material. In this investigation, stainless steel AISI 304 grade blanks of 1.0 mm thickness with different diameters are drawn into a circular cups ...

Process Parameter Effects on the LDR in Warm Deep Drawing of Magnesium Alloys

Key Engineering Materials, 2009
The present work is focused on the investigation of the role of temperature and punch speed in warm deep drawing of AZ31 magnesium alloy. To this purpose, an experimental campaign, defined using a proper DOE approach, has been performed. The experimental results, in terms of the Limiting Drawing Ratio, have shown that drawability is strongly affected ...

Warm deep drawing of magnesium alloy sheets — formability and process conditions

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2008
The influence of deformation conditions on the formability of magnesium alloy was systematically investigated using the experimental method and finite element analysis. The research activity aimed to gain further insight into the formability of magnesium alloy AZ31 (aluminium 3 wt per cent, zinc 1 wt per cent) and to have first-hand knowledge of the ...
