Experimental determination of the limiting bulge height in hydromechanical deep drawing
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2008Owing to fluid pressure, the unsupported blank between the punch and the drawing ring is bulged in the direction opposite to the punch movement. The blank is thus drawn over a fluid cushion and does not contact the drawing ring profile radius. The bulge is hence advantageous for ensuring class A surface quality of the workpiece.

A Study on DOE Methods for Hydromechanical Deep Drawing Process Parameters
Applied Mechanics and Materials, 2012Formability of sheet metals can be increased by Hydromechanical Deep Drawing (HDD) process. Formability of the deep drawn cups is generally assessed by Limiting Drawing Ratio (LDR) which is the ratio of the blank diameter to punch diameter. In order to increase LDR by HDD, process parameters of the HDD should be arranged properly.

Analysis of rupture instability in the hydromechanical deep drawing of cylindrical cups
The International Journal of Advanced Manufacturing Technology, 2007This paper presents analyses of tensile instability in the hydromechanical deep drawing process of cylindrical cups. Analytical models are developed based on Barlat-Lian and Hill’s non-quadratic yield criteria and the maximum permissible fluid pressure, above which rupture occurs, is achieved, assuming plane strain tensile failure.

Forming Limit of Magnesium Alloy Sheet in Hydromechanical Deep Drawing
Advanced Materials Research, 2012The experimental research on the hydromechanical deep drawing of AZ31B magnesium alloy sheet was conducted in this paper. The deformation behaviors and the influence of internal pressure on its formability are investigated, moreover, the fracture behaviors of the obtained workpieces are discussed.
