Abstract: This is the third Workshop on Physics-Based Models and Experimental Validation funded by the European Union's Enlargement and Integration Programme with creep and plastic deformation of metals as the focus theme this year. In addition to provide a platform for collaboration and exchange of information between researchers in EU Member States and the target countries, the Workshop also aims to bring together students and international experts, scientists addressing more basic research with code developers and industrial end-users and to provide cross-cutting by involving scientists from different sectors such as nuclear, aerospace and automotive. Material is the key for the development of our future society such as new energy system, transport system and electronic equipment. The material properties, performance of components in different environments and associated material degradation mechanism depend on the microstructure and chemical composition of the material. By "physics-based" we refer to models that address microstructures and associated thermodynamic non-equilibrium mechanisms and processes at different length and time scales. Such models include molecular dynamics, dislocation dynamics and crystal plasticity. The basic foundation for such models were established in the 20th century but the further development and application to industrial problems is of more recent date thanks to the dramatic improvement of computational power. The ultimate goal is to combine several models, including continuum based phenomenological models, into a multi-scale approach to address complex material properties and also application to industrial components. Although one of the drivers for physics-based models is to replace the need for expensive material testing, experiments will be needed to develop, calibrate and validate physics-based and multi-scale models. Thus the integration of physics-based models and innovative experimental techniques are clearly coupled. The physics based models can be used for design of new materials with tailored properties or reducing the cost and time for development of new materials using physics-based models integrated with experiments. This research is therefore singled out as a key priority in broader research programmes. The Workshop consists of ten keynote lectures, 19 oral presentations and a Poster session with over 50 posters. New developments and applications of the various physics-based models as well as some cases for scale bridging will be presented. There are also presentations on specific experimental techniques and on some that address the applicability for industrial applications.
