IDENTIFICATION OF THE YIELD SURFACE FOR SHEET STEEL USING AN OPTICAL MEASUREMENT SYSTEM
Abstract
The usage of full-field deformation data from experiments for the identification of material parameters is a topic of current research. The continuous improvement of optical measurement systems leads to promising results in parameter identification and optimization. With the high amount of data points the displacement and deformation field is not only a mean value but can be resolved locally which leads to a higher accuracy of the identified parameters.<BR />The goal of this research is to get reliable results from the full-field measurement data through a Finite Element Model Updating Method with a lower amount of experiments compared to taking the yield values and Lankford coefficients for the characterization of the yield surface of sheet steel.
