Abstract:
This paper describes a method to measure the flow curve which undergoes necking and normal anisotropy as a function of equivalent strain using an optical measurement system. The flow stress was determined by modifying Siebel and Schwaigerer's model. Normal anisotropy was regarded as a function of equivalent strain. Comparing with the experiment of the stretch forming process, the simulation using improved material properties shows the better strain distribution than the results using conventiona...     »
