Abstract

The application of complex fiber reinforced composite structures is increasing. This calls for a better understanding of the behavior of these structures, including the propagation of damage. In this research a secondary bondline failure model was developed as part of a failure prediction tool. Validation against laboratory experiments of hat stiffened panels in shock loading conditions showed good results. Also the application of the model in a large scale ship structure demonstrator gave reasonable agreement with previous experiments
