DESCRIPTION:Tian Yang (ECPS - EPFL)\nAbstract:\nStructure buckling is enor
 mously sensitive to imperfections\, so that predictions of buckling loads 
 based on linear stability analysis are usually overestimated. Reconsiderin
 g buckling problems within the framework of dynamical system theory\, a ba
 sin of attraction is defined for the unbuckled state while all the states 
 outside the basin boundary will finally evolve into the buckled state. By 
 analyzing the behavior of one structure under finite-amplitude perturbatio
 ns\, we are able to gain insights into its basin of attraction\, then pred
 ict its buckling load nondestructively. Relevant research on arc buckling 
 problems is demonstrated in this presentation\, which will be extended to 
 shells as the next step.\n\nBiography:\nTian obtained his bachelor and mas
 ter degrees in Aeronautics from Beihang University. In 2021\, he joined th
 e ECPS lab in EPFL as a PhD student under the supervision of Prof. Tobias 
 Schneider. Currently\, Tian is devoted to studying structure buckling prob
 lems with the knowledge of dynamical system.
