Three-dimensional crack growth in multi-layered architectures for automotive plain bearings.
In, 12th International Conference on Fracture, Ottawa, Canada,
12 - 17 Jul 2009.
The assessment of shielding and anti-shielding effects on crack growth in multi-layered architectures is achieved using elasto-plastic finite element models. Initially, the evolution of straight, deflected and bifurcated cracks is studied through two-dimensional models with blunted crack tips using the maximum tangential strain as a criterion for deflection and the crack opening displacement as the crack driving force. The methodology is extended to three dimensions assuming only elastic material behavior; some initial analysis results on the effects of shielding along the crack front are presented and discussed
