“Focusing on the head of the drop instead of the tail, the current study found that the compressive stresses in the glass are about 50 tons per square inch, which gives it the strength of some steels. … in a Prince Rupert’s drop, the interface between the inner and outer regions deflects the forces sideways, so the crack can’t propagate?
Rev, what’s the stress tensor doing?
