Abstract
Recent advances in light weight material systems have expanded the application range over which adhesively bonded composite joints are used. Wind turbine blades are one of the areas of application, which need to be analysed to increase the effciency and aid in the future blade de-velopment. The current master thesis focuses on the development of a parametric model for the analysis of adhesive bonding. A local parametric model is developed for single lap probe and orthotropic laminates with adhesive bonding. It is validated against the available numerical results of a non-parametric model. The model is then tested for parameters of discretization, adhesive thickness, coupling offset and orthotropic stacking through simple user inputs, which otherwise would have required more effort and time via conventional non-parametric modelling approach. Following which, the local model is coupled with an already parameterized global wind turbine blade model. The interaction of the global-local approach and the effects at both scales are studied and the results are analyzed and documented.
