It is said that a weak link determines the strength of the entire chain. Likewise, defects or small cracks in a solid material may ultimately determine the strength of that material - how well it will withstand various forces. For example, if force is exerted on a material containing a crack, large internal stresses will concentrate on a small region near the crack's edge. When this happens, a failure process is initiated, and the material might begin to fail around the edge of the crack, which ...
