Abstract

Some results are presented on an ongoing experimental, ballistic and numerical characterization of a novel new armour steel with comparison to a leading commercial benchmark alloy. The apparent better resistance to plugging failure of the new steel is shown with comparative ballistic tests over a range of plate thicknesses for two types of projectiles. Split Hopkinson Pressure Bar tests in compression and tension as well as a series of quasi-static tensile tests were performed to characterize the dynamic plasticity and failure of the materials.

Acknowledgments

The authors thank Dr. R. J. Mostert and Dr. P.H.G. Pistorius for all the informative discussions as well as T. Cloete of the Blast Impact Survivability Research Unit at the University of Cape Town for the help with specimen design and SHPB tests. The very kind help of Mr. J. Calitz of Eskom Research and Innovation Centre in the tensile tests was exceedingly valuable. Partial funding by the NRF through the Technology and Human Resource for Industry Program is appreciated. Partial funding by the Damascus Armour Development Consortium through the Innovation Fund (currently the Technology Innovation Agency) (Project no. T70044) is also appreciated. Finally, permission to publish from the University of Pretoria and the Damascus Armour Development Consortium is acknowledged.
