| Abstract: | The lifetime distribution of a component containing notches of various shapes is determined both in a fatigue test and using numerical simulation. The simulation model is based on the ideas of probabilistic fracture mechanics with an underlying simple fracture mechanics model for void defects. A postprocessing tool is used to determine the failure probability given the stress field in the component. |
