TOWARD A MULTI-LEVEL EVALUATION OF BONDED REPAIRS FOR COMPOSITE ASSEMBLY: SHEAR CHARACTERIZATION
Résumé
An innovative bonded repair evaluation, through the design of a detail-sized evaluator and representative from the industrial application, is proposed thanks to the study of the interface behaviour. This paper deals with a primary major phase which is necessary to get “elementary”, uncoupled and local information. This work is done following three stages: First, a 3D numerical model has been designed to address an adequate geometry for the coupons. Secondly, non-standard shear tests (due to non-standard geometry) have been conducted. Some geometrical data have been measured. Finally, using the results of this geometrical evaluation, a 2D numerical modelling strategy, has been developed to be as light as possible and compared to experimental results The low-time consuming numerical model will be helpful for the future numerical design of the bonded repair evaluator.
