Abstract
Finite element simulation of stretch flanging process was carried out in order to investigate the effect of
process parameters on maximum thinning (%) in stretch flanging process. Influences of initial flange length, punch die
clearance, width of sheet metal blank and blank holding force were investigated on maximum thinning (%). Finite
element simulation was done using FEM software package ABAQUS. Sheet metal blanks of AA 5052 were utilized for
numerical simulation of stretch flanging process. Mesh convergence study was carried out to ascertain the accuracy
of present FEM model. It is found that circumferential strain and shell thickness decreases with decrease in initial
flange length and punch-die clearance while both decreases with increase in blank-holding force. Radial strain
increases with decrease in initial flange length and punch-die clearance and with increment in blank-holding force and
width of sheet. It is found that width of sheet metal blank and blank holding force have greater influence on maximum
thinning (%) as compared to initial flange length and punch die clearance.
