Small-Scale Experimental Study of the Effect of Nonstructural Mass on Debris Impact Forces
Small-scale experimental tests have been carried ou t to investigate impact forces when flexible debris hit a relatively rigid structure. The tests involved HSS2×2×1/8 steel tubes of two and three meters in length impacting a load cell. The tests herein are an extension of work by Paczkowski et al. (2012). As compared to those tests, the tests herein included a more detailed measurement of stra ins in the projectile, as well as ‘nonstructural’ mass added to the steel tube. The purpose of this additional mass was to gain an initial understanding of how the mass of contents inside a shipping container might affect impact. Analysis of the new tests supported the findings pr esented in Paczkowski et al. (2012).
