Abstract EN

The aim of this paper is to design and fabricate a star die and a cylindrical die to produce a star shape by redrawing the cylindrical shape and comparing it to the conventional method of producing a star cup drawn from the circular blank sheet using experimental (EXP) and finite element simulation (FES).

The redrawing and drawing process was done to produce a star cup with the dimension of (41.5 × 34.69mm), and (30 mm).

The finite element model is performed via mechanical APDL ANSYS18.0 to modulate the redrawing and drawing operation.

The results of finite element analysis were compared with the experimental results and it is found that the maximum punch force (39.12KN) recorded with the production of a star shape drawn from the circular blank sheet when comparing the punch force (32.33 KN) recorded when redrawing the cylindrical shape into a star shape.

This is due to the exposure of the cup produced drawn from the blank to the highest tensile stress.

The highest value of the effective stress (709MPa) and effective strain (0.751) recorded with the star shape drawn from a circular blank sheet.

The maximum value of lamination (8.707%) is recorded at the cup curling (the concave area) with the first method compared to the maximum value of lamination (5.822%) recorded at the cup curling (the concave area) with the second method because of this exposure to the highest concentration of stresses.

The best distribution of thickness, strains, and stresses when producing a star shape by redrawing the cylindrical shape into a star shape
