Bonded composite repairs are efficient and cost effective means of repairing cracks and corrosion grind-out cavity in metallic structures, and composite structures sustained impact and ballistic damages, especially in aircraft structures. This book grew out of the recent research conducted at the Boeing Company and the Defence Science and Technology Organisation (DSTO, Australia) over the past ten years. Consequently it is predominately a compilation of the work by the authors and their colleagues at these two organizations on the design and analysis of composite repairs. Composite Repair is entirely devoted to the design and analysis of bonded repairs, focusing on the mathematical techniques and analysis approaches that are critical to the successful implementation of bonded repairs. The topics addressed are presentated in a sufficiently self-explanatory manner, and serve as a state-of-the-art reference guide to engineers, scientists, researchers and practitioners interested in the underpinning design methodology and the modelling of composite repairs.
