Fatigue life estimation of riveted joints using crack growth concept

Original language description

Fatigue life estimation of riveted joints with countersunk head was performed by the crack growth analysis and results were compared with the experimental observation. The multi-site damage (MSD) in the skin made from the aluminium alloy D16č ATV was assumed so that the simultaneous development of fatigue cracks emanating from holes in the same structural element was studied. The equivalent initial flaw size approach (EIFS) was employed. The series of ten simultaneously growing cracks was analysed by methods of linear elastic fracture mechanic and crack growth concept utilizing FASTRAN model. Stress intensity factors used in the crack growth law were determined from the finite element model created in ABAQUS FE package. Cracks evelopment under loading at several load levels was simulated. Assuming initial corner cracks of 0.125 mm in size, the analysis results show the fatigue lives close to the experimentally determined S-N curve of tested specimens. The considerable part of the fatigue life of the joint can be attributed to the crack growth. The analysis results exhibit that the smaller load level yields the longer crack initiation. The simulated fatigue life of tested specimens determined by the crack growth concept can be used as the upper bound for the design purposes in involved joint configuration very well.
