Spyridon Stouraitis is a Doctoral Candidate at the Norwegian University of Science and Technology (NTNU). Under the supervision of Associate Professor Mojtaba Mokhtari and the co-supervision of Professor Bernt Johan Leira, Professor Dong Trong Nguyen and Associate Professor Adnan Kefal (Sabanci University) he is developing an Inverse Finite Element Method for the Structural Health Monitoring of Marine Structures. This work focuses on developing a Finite Element-based approach utilizing an inverse formulation to reconstruct applied loads, stresses, and displacements in Marine Structures, by utilizing discrete measured surface strains. Upon completion, this research aims to deliver a robust, comprehensive, and universally applicable methodology for effectively monitoring the structural response of various types and sizes of vessels and floating offshore wind turbines.
In terms of his academic background, he has attained both his Bachelor’s and Master’s degrees in Naval Architecture and Marine Engineering from the National Technical University of Athens (NTUA). Under the supervision of Professor Emmanuel Samuelides, his Master’s thesis focused on the Strength Assessment of Container Vessels. Specifically, eight different container vessel models subjected to various torsional and bending loading conditions were analyzed using the Finite Element Method (FEM). Additionally, an extended as well as comprehensive investigation of the modeling parameters was conducted and also evaluated the local strength of various structural components against compression, with particular emphasis on the buckling behavior of stiffened panels and stiffener elements from all the examined vessels. As an extension of his Master’s thesis work, he is currently investigating the progressive collapse of six different container vessels under combined loads, with vessel sizes ranging from 1,800 TEU to 18,000 TEU.
The following are his primary research interests, which encompass various aspects of Marine Structural Analysis and Computational Modeling:
- Structural Health Monitoring (SHM) of marine structures.
- Numerical simulation of fluid-structure interaction for the assessment of structural loads on hull girders.
- Computational methods for solution of inverse problems in mechanics.
- Numerical simulation of complex systems under compound stresses.
- Numerical methods for the solution of ill-posed problems.
- Computational modelling of linear and non-linear phenomena.
- Estimation/determination/assessment of maximum ship’s operation load.
- Multi-criteria assessment of ship-shaped structural design.
- Development of analytical formulas and iterative processes to estimate structural behavior characteristics.
- Applications of AI techniques (Neural Networks) in the prediction of structural behavior.
- Combined static and dynamic load response of marine structures.
Beyond his research pursuits, he is an avid all-mountain skier, an enthusiastic sailor with experience in offshore sailing, and an AIDA-3 level free-diver. Additionally, he holds certificates in classical music theory and specialize in Beethoven’s pianistic literature. He has received classical piano training at the Athens Conservatoire and the Piraeus Conservatoire under the guidance of the virtuoso Aikaterini Vazaiou. He is preparing for his classical piano proficiency certificate, focusing on the works of Ludwig van Beethoven, Sergei Rachmaninoff, Wolfgang Amadeus Mozart, Johann Sebastian Bach, Claude Debussy, Maurice Ravel, and Frédéric Chopin.
