DESCRIPTION:Philippe H. Geubell\, Department of Aerospace Engineering\, Un
 iversity of Illinois\nAbstract\nThis presentation summarizes the developme
 nt 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 deformabl
 e media\, structural-acoustic coupling\, flutter instability problems and 
 aeroelasticity-driven failure events in solid propellant rockets.\nThe tal
 k will focus primarily on the development of an accurate scheme used to tr
 ansfer fluid-induced loads across non-matching discretized interfaces and 
 its impact on the accuracy of the coupled solution. We will present the re
 sults of a detailed comparative study between the proposed method and exis
 ting load transfer schemes. This comparative assessment is based on a set 
 of FSI applications of increasing complexity involving flat and curved flu
 id interfaces. The last part of the presentation will focus on the on-goin
 g modeling activities in the area of structural/acoustic coupling.\n\nShor
 t Bio\nOriginally from Belgium\, Philippe Geubelle got his Ph.D. in Aerona
 utics at Caltech in 1993. After postdoc at Harvard\, he joined the Univers
 ity of Illinois in 1995\, where he is currently professor and associate he
 ad in the Department of Aerospace Engineering\, with joint appointments in
  Mechanical Science and Engineering\, and Civil and Environmental Engineer
 ing. He is also serving as Director of the Illinois Space Grant Consortium
 \, a NASA-sponsored higher-education program.\nHis research interests pert
 ain to the theoretical and numerical treatment of complex problems in soli
 d mechanics\, and\, in particular\, of quasi-static and dynamic fracture m
 echanics\, multiscale modeling of heterogeneous\, layered and MEMS materia
 ls\, composite manufacturing processes and computational design of novel b
 iomimetic materials. Other research activities involve computational aeroe
 lasticity and parallel programming.
