and punch velocity were regulated in real time using PID closed-loop control technique. The deep drawing test of 2.0 mm-thick molybdenum sheets with temperature of 870 °C and vacuum degree of 10-2 Pa...Trans. Nonferrous Met. Soc. China 22(2012) s254-s260 Development of thermal deep drawing system with vacuum environment for difficult-to-deformation materials MENG Bao, WAN Min, WU Xiang-dong, ZHOU......
of developing technology and the cost of testing die were reduced. WIFI[1] used updated Lagrangian formulation (ULF) to analyze the axisymmetric deep drawing of sheet metal forming problems when the material anisotropy and hardening properties are known. KORHONEN[2] developed the use of regional peak load of plastic flow theory to quickly accurately estimate the punch load in the deep drawing......
the test of stress-strain and forming limit curves were used as input into ABAQUS/Explicit finite element code to predict the failure occurrence of deep drawing process. The three parameters were...Formability improvement and blank shape definition for deep drawing of cylindrical cup with complex curve profile from SPCC sheets using FEMDuc-Toan Nguyen1, 2, Duy-Khoe Dinh1, Hong-Minh Thi Nguyen1......
