Fast Fracture

In structural engineering and material science, fast fracture is a term given to a phenomenon in which a flaw (such as a crack) in a material expands quickly, and leads to catastrophic failure of the material. Stress acting on a material when fast fracture occurs is less than the material's yield stress. A very representative example of this is what happens when poking a blown up balloon with a needle, that is, fast fracture of the balloon's material.

Famous quotes containing the word fast:

    The Fountaine of parents duties is Love....Great reason there is why this affection should be fast fixed towards their children. For great is that paine, cost, and care, which parents must undergoe for their children. But if love be in them, no paine, paines, cost or care will seeme too much.
    William Gouge (20th century)
