| The fracture of any material may be separated into (at least) two stages. The first stage is the initiation of a crack at an otherwise flaw-free surface (or in a flaw-free interior volume). The second stage consists of propagation of this flaw, causing eventual mechanical failure of the structural element. Separate and different testing procedures are used to determine the fracture initiation resistance and the fracture propagation resistance. (Author) |

The coverage is believed to be relatively complete insofar as the available, published world-wide literature is concerned. In addition to the bibliographic listings, a short review and appraisal of the contents of each reference is given. The report contains indices according to subject, author and nationality of the contributions; the periodical coverage of ... |

| The work accomplished under the first two contracts was concerned with the type of failure induced by overmatching fragment simulators, i.e., those having a diameter greater than the thickness of the armor, as this was considered the most severe condition to which the armor would be exposed. It was then desired to complete the picture by showing the abilities of armor materials to resist penetration by undermatching fragments, which may ... |

| This study includes the effects of various fragment nose shapes, angles of incidence, higher velocities and smaller fragments. It was found that the previously developed formula for predicting light armor performance remains valid over the extended range of conditions for most of the materials studied. It is shown that the original formula can be modified to enable a designer to account for the effect of angle of incidence for metallic ... |

| Investigations of the performance of single plates of aluminum and steel wre undertaken from which an empirical method was derived for evaluating performance on the basis of several static and dynamic tests. For the case of over-matching projectiles and the range of tests investigated, the method gives results which are in reasonable agreement with experimental measurements. The testing of single aluminum plates enclosed in nylon duck sacks of from two ... |
