Surface morphology evolution in stressed solids: Surface diffusion controlled crack initiation
1994
Journal of the mechanics and physics of solids
We present a nonlinear analysis of the temporal evolution of the surface morphology of a stressed solid based on a general parametric description of the surface shape. We find that surfaces of elastic, defect-free solids are unstable against the nucleation and growth of cracks. The rate at which this surface instability occurs depends on the material transport kinetic mechanism. The surface instability creates a groove that sharpens as it grows deeper. The groove growth rate accelerates until
