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