Elastic-plastic material behavior of shock-loaded Al-composites

Abstract

The dynamic behavior of Aluminium reinforced with different ceramic fibres has been investigated using planar plate impact technique in connection with a velocity interferometer VISAR. The measurements are part of a program to rank the protection capability of ceramic reinforced materials in light weight armor systems. Values of the Hugeniot elastic limit HEL and the spall strength have been determined. In the case of Saffil(Al2O3)/7075Al Us-up and o-e-diagrams have been calculated from experimental data. Microscopic examination of sample fragments from recovery experiments provide insight into the fragmentation processes involved
