个人简介：
Shaker Meguid is Professor and Director of the Mechanics and Aerospace Design Laboratory at the University of Toronto, Canada. His research activities have contributed significantly to Applied, computational and experimental mechanics in aerospace and automotive engineering, multiscale modelling, multifunctional nanocomposites, crashworthiness, fracture mechanics and failure prevention. He has published over 320 papers in leading tier-1 scientific journals, gave over 250 presentations in international conferences. He authored 3 books, edited 2 books & 22 international conference proceedings and contributed 8 book chapters. He won many awards over the years, including the Engineering Award-Research and Development by the Professional Engineers of Ontario, and the highest award by the European Society for Experimental Mechanics. He is also a fellow of the Engineering Institute of Canada.
讲座内容：
In this talk, Meguid will summarize some of his recent research on the structural integrity of aviation gas turbine engines (GTEs). These include studies concerned with blade disc interface stresses, thermomechanical failures in thermal barrier coatings (TBCs), instability challenges in aerial refueling and multifunctional nanocomposites. This will be followed by an extended coverage of single and multiple blade shedding that could lead to catastrophic GTEs failures. Accordingly, Meguid will address three layered topics: (i) identifying the kinematic trajectory of the released blades both numerically using nonlinear finite element simulations and experimentally using a newly designed and instrumented scaled down test rig. (ii) Determining the energy absorption and containment capabilities of a number of alternative materials. (iii) Finally, he will share his novel bilayer containment ring design accounting for the interaction between the released blade and the trailing blades in a fan disk.
