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 using1) 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 systems2) 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.
