Fragmentation of Solid Materials Using Shock Tubes. Part 3: Second Test Series in a Small Diameter Shock Tube

Abstract

This report describes a series of tests that used an explosively-driven small-diameter shock tube to shatter simply-supported plates with relatively high-pressure, long-duration blast loads. To determine how the fragment size distribution changed with time due to, e.g., collisions between fragments, the fragment size distribution was measured at two different times. These tests varied the load, sample material, sample thickness, sample strength, and the volumetric density of fragments impinging on the collection device. As a result, these tests obtained a range of different fragment size distributions. By contrast, an earlier test series with fewer variables obtained only a single fragment size distribution.
