scillatory transient forces present that much influence and sometimes dominate crack initiation and propagation. Under these conditions, the forces acting on the crack initiation site can be significantly different to those seen by sensors placed in the striker or support points for the specimen.

The good agreement between the experimental results and the transient higher-order asymptotic analysis clearly indicates that the contribution of the non-singular terms to the total stress and deformation fields is significant.

Pertinent experimental and numerical results are also presented.

It is found that the impact fracture toughness thus determined increases with the decrease in time-to-fracture, and depends on the incident wave form when the loading rate is high. These results are discussed based on the time dependent stress field near the crack tip.
