New methods for more accurate material characterization

In order to ensure better process design and tool optimization, it makes sense to describe material behavior in the context of phenomenological plasto-mechanics. To achieve this, it will be necessary to determine material behavior comprehensively and also to a high level of precision, in order to determine accurately the start of flow and to put forward specific variables relative to the forming process. At Fraunhofer IWU these endeavors have been expanded to form a main research area, with the aim, for example, of making the necessary material variables available under actual process conditions, detailed and accurate, for a range of different simulation programs.
