In about 2005, I read in Science News about work done by Andrew Belmonte at Penn State on this very question. It's getting late, so I'll let others Google it and dig up info, but this should get you started. Bob --- Hilarie Orman wrote:

it fails along a diameter--the widest point? Presumably, sufficient elongation parallel to that diameter will bifurcate the line of probable failure. E.g., is there a shape that half the time breaks 1:2 and half 2:1? Convex? Could it be an ellipse? Is there a shape where the crack might be uniformly anywhere? --rwg
