Avalanche cracks may appear globally supersonic while remaining locally subsonic
Can a crack be supersonic? Can the fracture that triggers an avalanche propagate faster than the limiting velocity predicted by classical fracture mechanics? The question remains the subject of debate within the scientific community. While some numerical and experimental studies suggest that avalanc...

Can a crack be supersonic? Can the fracture that triggers an avalanche propagate faster than the limiting velocity predicted by classical fracture mechanics? The question remains the subject of debate within the scientific community. While some numerical and experimental studies suggest that avalanche cracks may propagate at supersonic speeds, others offer a different interpretation.
