DESIGN OPTIMIZATION OF INITIAL BLANK SHAPE IN DEEP DRAWING PROCESS OF A CIRCULAR CUP

A blank shape optimization method is presented in this research for reduction of earring defect due to sheet anisotropy behaviour in deep drawing process by using the reduced basis technique coupled by finite element and design of experiments methods. The primary objective of the proposed method is to reduce the enormous number of design variables required to define the initial blank shape. This method is demonstrated on the blank shape optimization of deep drawing of a round cup.
