An experimental technique is presented for subjecting cracks to high rates of shear (mode-II) loading. The dynamic crack tip loading conditions are investigated for both the phase of loading and the subsequent phase of failure by means of the shadow optical method of caustics. Results that show the failure behavior observed at different rates of loading are reported.
