Contact damage was induced in zinc sulfide plates by pressing glass spheres into the surfaceshd The radial crack lengths (c) were measured and correlated with the applied load (P) using Pαd 1 f 112 , where d i is the contact diameter. This yielded an excellent correlation and showed a load threshold and a transition region in the near field, as expected. Pαc 3/2 yielded a poorer correlation.
