Recently, ESA prepared "Fracture Control Guidelines" for STS (Space Transportation System) payloads to meet NASA requirements. In this study applicability of fracture mechanics principles to fatigue crack growth and failure is discussed. Different effects such as threshold, fracture toughness and load ratio and the behaviour of short cracks are...

Applicability of rainflow counting to crack growth analysis of complex loading is discussed. The rainflow counting method can account for the effects of small and high loading cycles under spectrum loading conditions. A new incremental crack growth model which accounts for these effects is introduced. The model is compared with experimental...

Crack growth prediction methods were evaluated and a preliminary selection was made of models that appear to be applicable to ESA space structures. In this report a plan is formulated for verification of the candidate models. Test configurations, materials and initial defects are specified as well as experimental procedures to be used for...

At the NLR the CORPUS model was developed for prediction of fatigue crack growth under variable amplitude loading. In this document the different versions and areas of application are discussed. Problem areas in the applicability of the models are indicated and suggestions for improvement are made. In addition a Hybrid formulation is developed...

Utilising the NLR Stripyield cycle-by-cycle fatigue crack growth model a basic description of the time dependent effects associated with periods of constant load level has been added to model Fatigue-Creep interactions. An outline of the basic Creep model is given along with flow diagrams of the sub programs added to the Stripyield model. Other...

Multiple Site Damage (MSD) is a typical problem for ageing civil and transport aircraft, where the large number of fuselage pressure cycles may cause fatigue cracking at multiple rivet locations. The residual strength of a panel with a leading crack and MSD cracks is lower than that of a panel with the same leading crack but without MSD. This...

At NLR models are developed for prediction of fatigue crack growth under variable amplitude loading. The models, computer programmes and specific areas of application are discussed. Results obtained using the software are compared with experimental data available for the same configurations. References for a more detailed description of models,...
