Abstract

This report evaluates capabilities and limitations of the different methods using experimental results from literature and elaborates on a method which could minimize current deficiencies without having severe impact on the huge amount of already existing evaluations and data. These methods should have the capability to introduce stress-strain curves in future code editions.
