In the present study the effect of mechanical Properties like strain hardening coefficient (n) and yield strength (σys) on the deep drawing formability is observed. In which three levels of n and σys have been considered. All the simulations were performed in the PAM STAMP 2G a FEM code and specialized sheet metal forming soft. Hill’s 1948 isotropic hardening yield criterion was used as the plasticity model. Hollomon’s power law was used as the strain hardening law. All three levels of mechanical properties were taken from experimental work of Singh and Gupta (2010) on IF steel. The data like dome height, and thickness distribution variations is taken. The results showed that dome height for the all the simulation is same and thickness distribution has got little variation with respect to mechanical properties.

Keywords: Sheet metal forming, Deep drawing, simulation, formability, dome height, thickness distribution.
