Results of tests to be used for verification of advanced crack growth prediction models

In this report the experimental procedure is described and results are given of tests for verification of advanced crack growth prediction models. Testing involved constant amplitude fatigue loading at R = 0.1 and R = 0.5. In a similar test series loading was interrupted at regular intervals for application of overloads or overload/underload...

Results of verification of crack growth models (Work package 7 of ESA contract 5826/84/NL/PB(SC))

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 predictions based on the candidate models are verified by comparison with experimental results. Test configurations, materials and initial defects are specified as well as the load...
