摘要：In this present work, finite element analysis (FEA) is applied to simulate cold tube drawing process with a fixed plug for AISI 1010 steel tube. The effects of reduction of area, semi die angle, semi plug angle, and friction coefficient on drawing stress are studied. The finite element model is successfully validated with the experimental data at reduction of area 16%. Results indicate that a good agreement between the experimental and the finite element analysis (FEA) is found. Consequently, the effect of semi die angle on plastic deformation is larger than the semi plug angle because of the bigger size of the semi die angle. Semi die angle of 12° gives minimum drawing stress for all coefficient of frictions. A semi plug angle between 2° and 4° should be used in tube drawing process with a conical fixed plug when semi die angle is equal to 7°.
