Shock wave interactions at explosive/metallic interfaces
<p>"Metallic tubes filled with C-4 high-explosive and constructed of either aluminum or copper were tested during this study of high strain rate effects within thin metal cylinders performed as an adjunct to helical flux-compression generator research at the University of Missouri-Rolla. This study …

The influence of caprock on blast fragmentation distribution
<p>"This dissertation describes the development of a small-scale model of a caprock-laden quarry blast and discusses the results from that testing. The purpose of this testing was to provide insight into the reasons for poor caprock breakage during blasting.</p> <p>Small-scale test blocks were …

The behavior of sUAS under explosive loading conditions and implications for safe operating procedures
<p>"Drones are increasingly being used for tasks previously unimagined and the beneficial uses are evolving. The United States Congress has envisioned the possible uses of drones for both combating and conveying explosive threats and other harmful and destructive activities. Congress' intent is …

Effects of Downwash when Measuring Gas Concentration with UAV-Mounted Gas Sensors
<p>"This research concludes that the downwash region of a rotary-wing unmanned aerial vehicle (UAV) does not produce pressure variations substantial enough to cause significant changes in density-based gas concentration measurements. US regulations evaluate gas concentration as a function of gas …

The mechanics of precision presplitting
<p>"Precision Presplitting is a widely used method of presplit blasting for the mining and construction industries. In recent years considerable effort has gone into the development of empirical equations based on field data to be able to better design the Precision Presplit for various rock types …

Pressure versus impulse graph for blast-induced traumatic brain injury and correlation to observable blast injuries
<p>"With the increased use of explosive devices in combat, blast induced traumatic brain injury (bTBI) has become one of the signature wounds in current conflicts. Animal studies have been conducted to understand the mechanisms in the brain and a pressure versus time graph has been produced. …
