Working Group 2
This WG will coordinate research related to the design of adhesively bonded composite structures taking into account geometrical configurations, new design features, fatigue and impact loading, creep phenomena, damage tolerance, imperfect bonding and environmental effects. Although a considerable amount of work has been already performed by researchers who developed several design algorithms, there is no generally accepted model yet. The objective of the WG is to propose a universal progressive damage algorithm that incorporates the aforementioned parameters and complies with the engineering allowable and design rules.
In order to meet this objective, the WG will perform the following tasks:
- Task 2.1. Explore new design concepts (geometrical configurations and new crack arresting design features).
- Task 2.2. Compare testing procedures for bondline characterization and model validation (under static, fatigue and impact loading, creep phenomena, imperfect bonding and environmental effects).
- Task 2.3. Evaluate different design methodologies for the structural behaviour and progressive damage analysis of adhesively bonded structures.
The WG will meet twice per year, for addressing the above mentioned tasks. The WG will organize two Training Schools in order to provide intensive training on different design methodologies and progressive damage analysis of adhesively bonded composite structures. Part of the training will be a series of lectures by experts. The lectures will be recorded and be available as ‘e-courses’ on the website of the project and the YouTube channel. An invitation will be published on the website and will be disseminated to Action’s peers.
The WG will deliver the content of the Training Schools (e-courses and state-of-the-art) in the 1st half of Year 1 and open-access publications concerning the tasks. In addition, a trade-off matrix for the different testing procedures and models for the bondline characterization will be delivered.
