摘要：

The surface of an elastically stressed solid is shown to undergo an instability in which deep, cracklike grooves form by surface diffusion. These grooves sharpen and accelerate as they deepen. The resultant morphology is an excellent agreement with recent experimental observation in several disparate materials systems.
