Improvement of the "corpus" crack opening model in the "ESA crack" software for damage tolerance analyses: Task report 2.1, Model development

de Koning, A.U. (author), Richmond, M.J. (author)

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...

Prediction of fatigue crack growth including effects of accelerated and retarded crack propagation

de Koning, A.U. (author)

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,...

Crack growth under sustained loads in aerospace materials

de Koning, A.U. (author)

In this report aspects of crack growth under sustained loads in aerospace materials are considered. Some models developed for a description of processes affecting the crack growth rate are discussed. Relevant natural and Induced environments are summarized as well as the material behaviour observed under these conditions. In a separate section...

Prediction of low and high crack growth rates under constant and variable amplitude loading

de Koning, A.U. (author), Dougherty, D.J. (author)

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...
