The computation options realized included either of the two different strip yield model implementations available in NASGRO and two types of the input material data description. The model performance has been evaluated based on comparisons between the predicted and observed results. It is concluded that altogether unsatisfactory prediction quality stems from an inadequate constraint factor conception incorporated in the NASGRO models.}, type={Article}, title={The NASGRO strip yield model predictions on fatigue crack growth for aircraft aluminium alloys under constant amplitude and variable amplitude programmed and random loading}, URL={http://journals.pan.pl/Content/124986/PDF/7_MECHANICAL_52_2005_4_Skorupa_The_nasgro.pdf}, keywords={fatigue crack growth, prediction models, alluminium alloys}, }
