Dynamic crack propagation in Homalite-100 was studied by moire interferometry in combination with high-speed photography. Crack opening displacements (COD) were measured as a function of distance from the crack tip by using moire interferometry fringe patterns. Crack velocities were also measured to correlate with COD. The results showed that the crack opening shape approaches a parabolic crack tip opening displacement with increasing crack velocity.
