What happens when a crack gets trapped by an obstacle of higher fracture energy?

The crack adapts instantaneously its propagation speeds. The speed jump amplitude is governed by the crack tip energy balance, as predicted by brittle fracture theory.

Friction is Fracture

The onset of frictional motion is characterized by the propagation of slip fronts, which – like cracks – break the discrete contacts at the frictional interface allowing sliding to occur. In this study, we combine friction experiments with fracture-mechanics simulations and theory to study long sought-after interface properties, such as local fracture energy and frictional peak strength.
