Advances in Ships and Marine Structures
The marine environment is a harsh environment. Extra care is required for marine structures due to fatigue loading, corrosive environment, etc.; otherwise, undesired consequences can occur and cause human life losses, economical losses, and environmental pollution. To minimise such risks and take necessary actions before catastrophic consequences occur, it is important to continuously monitor the health of marine structures by using sensors located at different parts of structures and establishing their “digital twin”. There are various structural health monitoring approaches available for this purpose. In this webinar, a new methodology, known as the inverse finite element method (iFEM), will be presented. The iFEM has various advantages; it is fast and robust, which makes it suitable for real-time monitoring. Moreover, it is not necessary to measure the loads acting on the structure, which may not be an easy task under operational conditions. The iFEM has been utilised for different marine structure types, which will be demonstrated as part of this webinar. In addition, the importance of the location and number of sensors will be highlighted.
While the iFEM is a useful technique for detecting damage in a structure, it is also important to predict how damage can evolve with time. Fracture and failure prediction is a challenging research area. There are various methods available for this purpose, including the well-known finite element (FE) method. The FE method is a powerful technique for the deformation and stress analysis of structures. However, it has various disadvantages in predicting failure due to its mathematical structure. In order to overcome this problem, a new computational technique, peridynamics, has been introduced. Peridynamics is a meshless approach, and it is well suited for predicting crack initiation and propagation in structures subjected to different types of loading and environmental conditions. In this webinar, various applications of peridynamics for marine structures will be demonstrated. Moreover, the homogenisation of polycrystalline ice by using peridynamics will be presented. Finally, the utilisation of offshore renewable energy for resolving the water scarcity problem will be discussed.
