Abstract
This presentation summarizes the development of a novel numerical treatment of coupled multiphysics problems, with emphasis on the simulation of transient fluid/structure interaction (FSI) events, such as the propagation of shocks and blast waves along deformable media, structural-acoustic coupling, flutter instability problems and aeroelasticity-driven failure events in solid propellant rockets.
The talk will focus primarily on the development of an accurate scheme used to transfer fluid-induced loads across non-matching discretized interfaces and its impact on the accuracy of the coupled solution. We will present the results of a detailed comparative study between the proposed method and existing load transfer schemes. This comparative assessment is based on a set of FSI applications of increasing complexity involving flat and curved fluid interfaces. The last part of the presentation will focus on the on-going modeling activities in the area of structural/acoustic coupling.
Short Bio
Originally from Belgium, Philippe Geubelle got his Ph.D. in Aeronautics at Caltech in 1993. After postdoc at Harvard, he joined the University of Illinois in 1995, where he is currently professor and associate head in the Department of Aerospace Engineering, with joint appointments in Mechanical Science and Engineering, and Civil and Environmental Engineering. He is also serving as Director of the Illinois Space Grant Consortium, a NASA-sponsored higher-education program.
His research interests pertain to the theoretical and numerical treatment of complex problems in solid mechanics, and, in particular, of quasi-static and dynamic fracture mechanics, multiscale modeling of heterogeneous, layered and MEMS materials, composite manufacturing processes and computational design of novel biomimetic materials. Other research activities involve computational aeroelasticity and parallel programming.
