Supersonic crack propagation in blocks of polymethyl methacrylate

  • R. V. Gol'dshtein
  • N. P. Novikov


It is shown that a giant laser pulse can cause supersonic crack propagation in PMMA. The results of the experiments and a microstructural analysis of the fracture surface are presented. A study of the microstructure shows that supersonic crack propagation is associated with the propagation of a shock wave in the focal region.
