Papers read at the symposium on damage tolerance in aircraft structures, in Toronto in 1970 are here collected between hard covers. Altogether they review the state of aircraft structural analysis for structures with propagating cracks and present recent advancements in research into basic mechanisms of crack propagation and residual strength of aircraft structures. The papers also provide a review of fracture mechanics as applied to the assessment of structural vulnerability and residual strength of materials and structures. To achieve this, the papers fall into the categories of basic concepts in fatigue crack propagation, effects of panel geometry, influence of panel stiffeners and application of fracture mechanics and crack propagation to the design and test of aircraft structures.
