Comparative study of conventional and hydromechanical deep drawing processes based on finite element analysis

Abstract

A two-dimensional finite element analysis has been performed to investigate hydromechanical and conventional deep drawing processes. The effects of the fluid structure interaction on the material formability, the strain and the thickness distributions are investigated. Large plastic deformation is observed in the plank at the bottom and the corner of the punch. Plastic deformation distribution results show a difference between the hydromechanical deep drawing process and the conventional deep drawing which is due to the friction effect. This latter represents one of the major features of the hydromechanical deep drawing process. Concerning the formability of the blank, the obtained results show that the hydromechanical deep drawing process gives a better formability than the conventional deep drawing process.

Investigation of Sheet Thickness and Punch Force in Die Surface Angled Hydro-mechanical Deep Drawing Method

“…The 5th and 6th points coinciding the punch nose radius zone of the cup (Fig. 3) are the zones where the thinning is the most due to the greatest stress occurring [7,14,29]. The allowable thinning ratio for cup wall thickness change in the hydromechanical deep drawing method is between 20% and 25% [7,30,31].…”

“…They also stated that sheet thickness thinning is less in sheet materials exposed to lower tensile force on larger surfaces. Abbadeni et al [14] Analyzed conventional and hydro-mechanical deep drawing processes using two-dimensional finite element analysis using AA5086 aluminum material with 1.12 mm thickness. They used ABAQUS package program for numerical analysis.…”

Improvement of Formability of AISI 1006 Sheets by Hydroforming with Die in Square Deep Drawing

“…The results demonstrate that while hydroforming deep drawing requires higher forces, it allows for achieving higher drawing ratios. In their study, Abbadeni et al [18] conducted a comparative analysis between the CDD process and the HDD process using finite element analysis. The research focused on examining the effect of fluid cavity pressure on formability, plastic strain, and thickness distribution.…”

Measuring Deformation of Deep Drawing of Various Alloys by Image Processing Using Matlab

“…Strain value is a base element for material testing, design optimization, process as well as product optimization, etc. So strain plays virtual role for engineers to introduce a system to find such property which can suit for all field environment [1] with robust, easy and latest technological way. Studies on metals and non-metals are carried out for its strength and based on the test results the other properties of those materials are realized.…”
