Investigation of deep drawing of square cups using high-strength DP600 and DP800 sheets

This study investigated the deep drawing of square cups using high-strength du-al phase DP600 and DP800 sheets via both experimental finite element meth-ods. The limiting ratio (LDR) wall thickness distribution were exam-ined. initial materials used in was equal to 1-mm. experiments carried out at room temperature Teflon film graphite spray lubricants same time. In terms LDR, numerical results corresponded with each other. A 1.97 LDR reached for steel 1.92 DP800. Given that thick-ness between results, an accord over 90% noticed. For steel, lowest value 0.864 mm 0.87 mm. measured be 0.89 while found 0.88 conclusion, pre-sent paper proves can achieved very satisfying by methods.
