Abstract-The present work is aimed at studying the deep drawing process of pure copper sheet both experimentally and by finite element analysis technique. This is because pure copper is being considered as a promising alternative for high strength steel and aluminium within many industrial applications because of its high density, high specific strength and material renowned for its excellent electrical and thermal conductivity, as well as its ductility and malleability. The thickness of the as received pure copper sheets is 1mm. In the present investigation, circular blanks of 85 mm, 88mm, 91 mm and 94 mm diameters are deep drawn at room temperature using 40 ton hydraulic deep drawing machine. Force-displacement curves were determined for all blanks using the integrated software. Formability of the metallic sheet is assessed by determing the limiting drawing ratio. LDR is defined as the ratio of the maximum blank diameter to the diameter of the punch. The diameter of blank just before the fracture occurs in the drawn cup is the maximum diameter of the blank. Higher the LDR more will be the formability. To understand the formability behavior of copper, deep drawing experiments have been conducted on a double action hydraulic deep drawing press and the drawability has been measured in terms of limiting drawing ratio (LDR). 3D Finite element models identical to experimental set up tools were developed for the simulation of circular cup deep drawing and simulations were carried out. The experimental and simulation results were found to be in good agreement.
