Numberical modelling and validation with fatigue tests.

A numerical model was developed using BEASY and was validated with fatigue tests data. The stress intensity factors (SIF) along the doubly curved crack front at different crack depths were obtained. With this model, a parametric study was used to investigate the influence of geometry, size and load case on fatigue life. Results showing both proportional and non-proportional sizing effects on fatigue strength were obtained.
