Title:
Determination of flow curves and normal anisotropy through tensile tests and optical strain measurement 
Abstract:
This article describes a method for determining the flow curve of thin metal sheet after uniform elongation, and the normal anisotropy as afunction of equivalent strain using an optical measurement system. The flow curve was determined with the help of a modified approach according to Siebel and Schwaigerer. In comparison to the results of biaxial forming processes, the numerical simulation using improved material data showed in the area of high elongation, in particular, a greater correspondenc...    »
