Researchers at the Racah Institute of Physics, Hebrew University of Jerusalem, have made a discovery that challenges the conventional understanding of fracture mechanics. The team, led by Dr. Meng Wang, Dr. Songlin Shi, and Prof. Jay Fineberg, has experimentally demonstrated the existence of “supershear” tensile cracks that exceed classical speed limits and transition to near-supersonic velocities. Their paper is published in the journal Science.
