Crack growth predictions using a crack closure model
Abstract
Crack growth predictions for through and corner cracks in 7075-T651 plate under constant amplitude loading and corner cracks under two variable amplitude spectra were made using a 'black box' crack closure program. The results were then compared with experiment and various parameters adjusted to give the best match to the experimental results. The optimum parameters chosen will be used for subsequent blind predictions to be made on this material and different but related spectra.
