Path differences between quasistatic and fatigue cracks in anisotropic media
Résumé
The propagation path of quasistatic cracks under monotonic loading is known to be stronglyinfluenced by the anisotropy of the fracture energy in crystalline solids or engineered materials witha regular microstructure. Such cracks generally follow directions close to minima of the fractureenergy. Here we demonstrate both experimentally and computationally that fatigue cracks undercyclic loading follow dramatically different paths that are predominantly dictated by the symmetryof the loading with the microstructure playing a negligible or subdominant role.
