Multiscale Fluid-Solid Interaction in Heterogeneous Materials and Interfaces
Funding:EU FP7 People - Marie Curie Actions: Career Integration Grant
Project Duration:Start Date: October 1st, 2012
Completion Date: October 1st, 2016
Summary:Fluid-solid interaction (FSI) governs nature. From soft tissue modeling to lubrication technology, FSI problems in biomechanics and engineering are a major challenge in computational science. This challenge is further intensified by the multiscale structure of materials and interfaces as well as by the finite configurational change (FCC) that a microstructure experiences under large deformations. The goal of this research is to investigate novel computational strategies for the modeling and analysis of multiscale FSI in heterogeneous materials and interfaces with FCC on all scales and homogenization as the core scale-transition technique. The examples that will motivate and guide this research are potential biological and industrial applications of the novel computational framework: (1) soft porous materials such as the articular cartilage that functions together with pore-level fluids in order to provide mechanical support, and (2) textured interfaces in bearings and polymeric seals that deliver improved tribological performance for rotating machinery.
