The repair of aerospace composite structures has, for the most part, neglected analysis of the damage prior to repair design. In the majority of repair cases to date an analysis of the criticality of the damage would have produced a much simpler repair. The analysis techniques currently available require extensive computations and, hence, computer support. The author has developed a simple analysis technique which can be used in the field, and does not require a personal computer. This simple analysis of hole damage is compared with the more complex and traditional techniques. The results show that not only is the simple analysis accurate, it can provide a better estimate of the hole stress state. This simple hole damage analysis method is very useful for in-the-field composite repair design and aircraft battle damage repair.
