DESCRIPTION:Dr Saeid Hedayatrasa\, Ghent University (UGent-MMS)\, Belgium
 \nAbstract\nHigh-performance composite materials have been increasingly us
 ed for manufacturing  structural components in different industries e.g. 
 aerospace\, automotive and wind energy. Given their layered multi-material
  design\, efficient inspection techniques are indispensable for reliable i
 dentification of production defects and in-service damage. In this present
 ation\, performance of different techniques in inspection of aircraft comp
 osite panels will be compared. Furthermore\, detection and quantification 
 of damage through full-field scanning laser Doppler vibrometry and sparse 
 array Guided Wave tomography will be presented. The limitations of the tec
 hniques and the potential of Physics-informed Neural Networks for more eff
 icient identification of damage will be discussed and the approach will be
  examined based on simulation data with added noise.\n\nBiography\nSaeid H
 edayatrasa is a senior postdoctoral research fellow at the Mechanics of Ma
 terials and Structures research group of Ghent University (UGent-MMS) in B
 elgium.  After getting a Master’s degree in Mechanical Engineering and 
 a few years of industrial and post-master research work in Iran\,  he com
 pleted his PhD in Mechanical and Manufacturing Engineering in October 2016
  at the University of South Australia. He was employed by the University o
 f South Australia until July 2017 as a research and teaching assistant\, a
 fter which he joined Ghent University as a postdoctoral researcher. He has
  computational and experimental background in design optimization and char
 acterization of acoustic meta-materials and composites. More specifically\
 , his research focus has been on analysis of vibrations\, elastic wave pro
 pagation and heat wave diffusion in advanced materials\, and their synergi
 c (vibro-thermal) interaction for non-destructive testing (NDT) and struct
 ural health monitoring (SHM). He is currently a visiting researcher at IMO
 S lab (EPFL) for a research collaboration on developing physics-informed d
 eep learning algorithms for damage quantification through vibrational meas
 urement data.  \n\n
