https://doi.org/10.1007/978-3-322-81699-3em in linear elastic fracture mechanics is the establishment of the stress intensity factor for the crack problem under consideration. Since the introduction of fracture mechanics much effort has been put into the derivation of stress intensity factors, and a variety of methods have been developed to approach the problem.

Fatigue crack propagation procedures have obvious shortcomings, but the prediction of fatigue crack propagation characteristics is even less accurate, despite the vast amount of research that has been done on this subject. Yet the developments achieved during the last decade justify a moderate optimism about the possibilities of prediction techniques.

Fracture resistance of materials discussion. For a perfectly brittle extension of this crack by cleavage, the criterion for crack propagation seems fairly easy. Cleavage failure occurs by the breaking of atomic bonds: consequently cleavage crack propagation can take place when the, stresses at the very crack tip exceed the interatomic cohesive forces.

Lobbying in der Europäischen UnionConsider a coordinate system . in a stressed solid. In each point (.) one can define the stresses σ., σ., σ., τ., τ., τ.. In a condition of plane stress σ. = τ. = τ. = 0. In a condition of plane strain ε. = 0 from which it follows that σ. = .(σ. + σ.).
