Abstract

In the present study, the effect of srain hardening exponent of material on flow characteristics, strain and damage distribution in sample and the load requred for the execution of the deformation process was investigated using finite element simulation. Results showed that the corner gap is not formed during deformation of ideally plastic material and the amount of equivalent strain is higher in the bottom side of sample compared with other regions. However, with increassing the work hardening exponent, the size of corner gap increases and the bottom side recieves less amount of strain. Also, damage factor in the sample of idealy plastic material is higher at the top side compared with other regions and the tensile stresses are applied on this area. Whereas, in the strain hardened material the higher damage factor was observed at the lower half of the sample. Finally, it was concluded that the pressing force increases with increassing the work hardening exponent.
