Abstract

A novel design principle is presented and tested, which is able to significantly improve the crack initiation loads of aeronautical composite panels with stringer terminations. Taking advantage of the stable crack growth in such structures, an artificial crack is introduced which enhances the combination of bolts and bond line, drastically reducing the strain energy release rate at the run-out tip and increasing the load transfer capability.
