Abstract

In recent years attention has focused on damage interaction, with particular emphasis on multi-site damage. Whilst most attention has focused on fuselage lap joints, related problems occur in composite structures which are subjected to multiple impact damage. This paper reveals that for composites there is little interaction between damaged regions, provided they are separated by more than one diameter. This methodology was verified via a coupon test program and an experimental evaluation of two damaged F/A-18 horizontal stabilators.
