SUMMARY:Aero-thermal-elasticity of plates in hypersonic flow
DESCRIPTION:Lecturer:Maxim Freydin\, PhD\n Faculty:Department of Aerospace 
 Engineering\n Institute:Technion – Israel Institute of Technology\n Loca
 tion:Classroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: https
 ://technion.zoom.us/j/93899557822\n Abstract: Fluid-structure interaction 
 in high-speed flow has seen an increased interest among researchers in res
 ponse to the worldwide race to sustainable hypersonic flight. The interact
 ion between inertial\, elastic\, aerodynamic\, and thermal loads in high M
 ach flows is an extension of classical aeroelasticity. To investigate the 
 fundamental physics that govern the aero-thermal-elastic interaction\, ela
 stic plates are utilized in wind tunnel experiments for their relative sim
 plicity of installation\, manufacture\, and analysis. Recent experiments i
 nvestigate the response of elastic plates using advanced measurement techn
 iques for pressure\, temperature\, and deformation. This enables a detaile
 d and direct correlation between theoretical and computational results cov
 ering a wide range of phenomena including shock-wave/boundary-layer and st
 ructure interaction\, flutter onset\, limit-cycle oscillation\, and imping
 ing shocks. In this talk\, a theoretical-computational model of plates in 
 hypersonic flow is presented\, and its use for the analysis of linear and 
 nonlinear static and dynamic problems is demonstrated. Recent extensions o
 f the model are presented with unsteady aerodynamic heating and piezoelect
 ric patches that double as strain sensors and structural elements. Importa
 nt parts of the structure and fluid models are emphasized through the lens
  of fluid-structure interaction including non-ideally clamped in-plane bou
 ndary conditions and turbulent pressure fluctuations.\n Details: \n
