Asphalt is a liquid, see e.g. https://en.wikipedia.org/wiki/Asphalt or https://en.wikipedia.org/wiki/Pitch_drop_experiment
Asphalt is also brittle, see e.g. this image:
My question is, what is required for a liquid to develop cracks when subject to a shock? Are all liquids subject to this?
I realize that defining "crack" in physical terms is a bit complicated. I also realize that even if they are formed, in low viscosity liquids the cracks will immediately "fuse" with the rest of the liquid. I was just puzzled about this. Is there, like a viscosity threshold for a liquid to become brittle?
