“Shape and stress sensing of offshore structures by using inverse finite element method”, Progress in the Analysis and Design of Marine Structures, pp. 141-148.
ABSTRACT: Stiffened thin-walled steel cylinders have been used as compression elements in the field of offshore structures for many years. On-site durability of these structures may suffer from the harsh marine environment. Therefore, a structural health monitoring system that provides real-time structural feedback of the structure is mandatory to ensure the safe operations of an offshore structure. Hence, this study investigates the applicability of a new state-of-the-art methodology, called inverse finite element method (iFEM), for displacement and stress monitoring of offshore structures for the first time in the literature. Displacement and stress solutions obtained from iFEM analysis are compared to those of reference solutions.
