Host Institution (HI) DANMARKS TEKNISKE UNIVERSITET
Country Denmark
Call Details Starting Grant (StG), PE8, ERC-2011-StG_20101014
Summary Imagine lighter and more fuel economic cars with improved crashworthiness that help save lives, aircrafts and wind-turbine blades with significant weight reductions that lead to large savings in material costs and environmental impact, and light but efficient armour that helps to protect against potentially deadly blasts. These are the future perspectives with a new generation of advanced structures and micro-structured materials.
The goal of INNODYN is to bring current design procedures for structures and materials a significant step forward by developing new efficient procedures for integrated analysis and design taking the nonlinear dynamic performance into account. The assessment of nonlinear dynamic effects is essential for fully exploiting the vast potentials of structural and material capabilities, but a focused endeavour is strongly required to develop the methodology required to reach the ambitious goals.
INNODYN will in two interacting work-packages develop the necessary computational analysis and design tools using
1) reduced-order models (WP1) that enable optimization of the overall topology of structures which is today hindered by excessive computational costs when dealing with nonlinear dynamic systems
2) multi-scale models (WP2) that facilitates topological design of the material microstructure including essential nonlinear geometrical effects currently not included in state-of-the-art methods.
The work will be carried out by a research group with two PhD-students and a postdoc, led by a PI with a track-record for original ground-breaking research in analysis and optimization of linear and nonlinear dynamics and hosted by one of the world's leading research groups on topology optimization, the TOPOPT group at the Technical University of Denmark.

Project Live Tapings of Material Formation: Unravelling formation mechanisms in materials chemistry through Multimodal X-ray total scattering studies

Summary With this proposal, I want to develop a new, multimodal approach to in situ X-ray scattering studies to unravel formation mechanisms of the solid state. The aim of the project is to develop a unified view of metal oxide nucleation processes on the atomic scale: From precursor complexes over pre-nucelation clusters to the final crystalline particle.
The development of new materials relies on our understanding of the relation between material structure, properties and synthesis. While the intense focus on ‘materials by design’ have made it possible to predict the properties of many materials given an atomic arrangement, actually knowing how to synthesize it is a completely different story. Material synthesis methods are to a large degree developed by extensive parameter studies based on trial-and-error experiments. Specifically, our knowledge of particle nucleation is lacking, as even non-classical views on nucleation such as the concept of pre-nucleation clusters do not apply an atomistic view of the formation process. Here, I want to use new methods in X-ray total scattering and Pair Distribution Function analysis to follow nucleation processes to establish the framework needed for predictive material synthesis. One of the large challenges in studying nucleation is the lack of a characterization method that can give structural information on materials without long-range order. I have demonstrated that time-resolved X-ray total scattering gives new possibilities for following structural changes in a synthesis, and the use of total scattering has opened for a new view on material formation. However, the complexity of the structures involved in nucleation processes is too large to obtain sufficient information from X-ray total scattering alone. Here, I will combine X-ray total scattering data with complementary techniques using a new multimodal approach for complex modelling analysis, providing a unifying view on material nucleation.
