Large strains, anisotropy of mechanical properties of materials and Coulomb friction in contact regions are some properties in the analysis of deep drawing process. In this research, the effects of different parameters such as anisotropy coefficient, work hardening exponent and friction coefficient on deep drawing process of drawing quality steel are studied. For this purpose, the finite element method (FEM) to simulate the process is used. A 2D finite element simulation (axis symmetric) in ABAQUS is done and the results are validated with valid appropriate reference. Then Forming Limit Diagrams (FLD) for different friction coefficients, different anisotropy coefficients and different work hardening exponents are obtained. Finally, changes in FLD are discussed and it is observed that the friction coefficient is the most effective parameter on FLD and anisotropy coefficient and work hardening exponent are the least effective parameters on FLD.
