Effect of Damage on Strength and Durability

Abstract

The effects of manufacturing and in-service defects and damage are an important consideration in the design of aerospace structures. These effects need to be fully understood for designing, manufacturing, and subsequent maintenance of aerospace structures. A thorough knowledge of the nature and extent of in-service damage plays a key role in designing proper and efficient repairs for the damaged components. The nature and extent of damage may govern the type of repair that needs to be performed, surface preparation for repair, extent of damage removal before performing repairs, and repair material selection. Various types of damages, including battle damage, in composites and their effects on strength and durability are discussed here. The extent of damage covered by damage tolerant design is also discussed.
