... Voronoi tessellations wherein each cell represents a material grain and the boundaries between them constitute the weak planes in the material. Fatigue cracks initiate on the weak planes where oscillating shear stresses are the strongest. Finite element analysis is performed to determine the magnitude...

... fatigue cracks propagate by a mechanism of shear decohesion in two slip bands (primary and secondary) near the crack tip in the direction of the maximum shear stress. The propagation rate for such a crack in the combined normal and shear (mixed-mode) loading can be determined by the following relations...
