Internal Fractures in Solids of Revolution Due to Stress Wave Focussingd. The initiation and growth of the internal fractures are associated with the focusing effect of P and S wave fronts reflected from the curved boundaries. High speed photography on perspex specimen is used for the verification of predictions of simple methods of geometrical optics and propagation o

The Effect of Strain History on Crack Initiation Under Dynamic Loadingnear and non-linear fracture mechanics (K. and J.). Results indicate that J. may be used in an initiation criterion. J. is reduced by pre-loading and it is smaller than the corresponding J. for the materials tested.

Comparison of the Flow Curves of 6061 Aluminum Alloy at High and Low Strain Ratesrings than in 1-in. rings. This size effect may be due to shock hardening, but a definite conclusion has not yet been reached. The -T6- temper rings also show a size effect, but the difference between the 1- and 2-in. rings was not the same for all values of flow stress.
