| Abstract | ||
| This work aims to study the effect of the blank holder force on strains and thickness distribution along cup wall of drawn part in deep drawing process. 2-D model of cylindrical cup of (40mm) outer diameter, and (0.5mm) thickness made from low carbon steel (1008–AISI), has been developed. A commercially available finite element package (ANSYS14.0) was used to perform the numerical simulation of deep drawing process. The experimental work carried out using digital image processing technique. Five values of blank holder force =5, 7.5, 10, 12, 15 KN) were adopted. The numerical results of this model were compared with experimental results and the results show that, the value of the thickness and hoop strain at cup rim decrease with increasing blank holder force, while radial strain increases with increasing blank holder force. The best thickness distribution over all zones in produced cup obtained when using blank holder force with value =10 KN). | ||
