Working Group 4
In-service Life Phase
Overview
This WG will coordinate research related to the in-service life monitoring of bonded structures, including bonded repairs. This WG will gather experts from the field of non-destructive testing (NDT) and structural health monitoring (SHM). The WG objective is to assist the development of a holistic approach that incorporates diagnostic and prognostic tools for the structural integrity and the remaining useful life of the structure, respectively. WG4 will work closely with WG1 and WG2 and will benefit from the outcomes that these two WG will produce.
Priorities
This WG will perform the following tasks:
- Task 4.1. Propose diagnostic tools for the structural integrity assessment of the bonded structure.
- Task 4.2. Propose prognostic tools for the remaining useful life of the bonded structure.
- Task 4.3. Develop guidelines towards bonded repairs application.
Activities
When possible, the WG will meet twice a year, for addressing the above mentioned tasks. The WG will organize an event, as a continuous learning process, which will consist of two Training Schools and STSMs. In the first Training School, the fundamentals of the diagnostic process will be presented (non-destructive evaluation and structural health monitoring). After that, STSMs will follow and the attendants will develop, with the guidance of experts, case studies for bonded composite structures on how to develop prognostic methods integrating the diagnostic tools with the design methodologies. The second Training School will be divided in two modules. In the first module, the STSM participants will present their cases studies, as peer-to-peer learning process. In the second module, the particularities of the bonded repair application will be presented. The WG will organize the Training Schools and STSMs. The WG will elaborate a list of definitions related with SHM/NDT techniques for in-service monitoring of composite bonded structures. Next the WG will draw up a list of SHM/NDT techniques for in-service monitoring of composite bonded structures. Also guidelines on the tools about diagnostics and prognostics and bonded repairs will be delivered.
Deliverables
The WG will deliver the content of the Training Schools (e-courses and state-of-the-art) and STSM (report of case studies). Guidelines on the tools about diagnostics and prognosis and bonded repairs will be delivered. As the interest from the scientific community about health monitoring of bonded structures is very high, the WG will present the outcomes of the activities in international conferences and open-access publications.
