Overview
Dr Sathiskumar Anusuya Ponnusami works as a Senior Lecturer in Structural Mechanics (Aeronautics) in the Department of Engineering at City, University of London since October 2018. Prior to City, he worked as a postdoctoral researcher in Solid Mechanics Group at the University of Oxford, where he was involved in developing computational models and data-driven machine learning tools for advanced composite fan blades within the Rolls-Royce University Technology Centre. He serves as the Programme Director for Aeronautical Engineering Programmes as well as the Deputy Admissions Tutor for Undergraduate Engineering Programmes.
He graduated with his PhD from Delft University of Technology (TU Delft) in the Netherlands. His doctoral research centered around computational modelling of fracture and healing in self-healing turbine composite coatings for aerospace applications supported by collaborative experimental development with material scientists. He also served as the leader of the team MultiFun, that won the £ 30,000 Airbus-UNESCO Fly Your Ideas Global Challenge 2015. He is also the awardee of the NLF Dutch Aerospace Award 2015 (University category, Netherlands), ITMA Future Materials Awards 2015 (WTiN, UK) and ICSHM Young Scientist Award 2013.
His research interests encompass computational modelling of damage and failure in multifunctional composite materials while his ongoing research exploits utilising machine learning tools for structural mechanics and composite materials engineering problems. Some of his current research topics include:
(1) Application of data-driven and machine learning techniques to structural mechanics, materials and engineering systems.
(2) Multiphysics modelling of multifunctional heterogenous materials (self-healing, energy harvesting and storage, actuation and sensing)
(3) Integrated numerical-experimental modelling for mechanics of composites
(4) Multiscale homogenisation and failure prediction.
(5) Reduced-order structural models (beams, plates, shells)
His main teaching activities cover subjects such as structural analysis, finite element method and composites at both undergraduate and postgraduate levels.
