Abstract
This paper is aimed to study the effect of material type on the drawing force. Three metals are used (low carbon steel 1008 AISI, Austenitic stainless steel 304 AISI, and pure aluminum 1100), as a sheet with thickness of 0.5mm for each one, and they were cutting as a blank with 80 mm diameter, then drawn in a die with 44mm diameter to produce cup. To predict the deep drawing force by finite element method, Hill's yield criteria is used, which examines the effect of anisotropy. Two dimension axisymmetry model of deep drawing were built and analyzed by ANSYS FEM code. The results show that the drawing force for stainless steel is higher than the other two metals due to the difference in metallurgical structure. The numerical results were compared with the experimental; good agreement was found between finite element and experimental results.
