The Manufacturing and Ballistic Testing of Tri-axial Quasi Three Dimensional Woven Composites Layered in Polyurea
… to this threat. This study investigates the ballistic resistance and self-sealing nature of a quasi 3D tri-axial woven composite layered with polyurea against high power rifle bullet impact. This is done by evaluating the effectiveness of quasi-3D tri-axial woven composites in resisting .50 …

The Role of Twinning in the Plastic Deformation of Alpha Phase Titanium
… the titanium alloy Ti–6Al–4V were subjected to ballistic impact testing at room temperature with a high strain rate of 10$^3$s$^–1$. In addition, a detailed analysis was conducted of three manufacturing processes of Ti–6Al–4V (wt. %) that are likely to cause deformation twinning: metallic shot …

Accelerated computational modeling of ballistic helmet test protocols
… their threat mitigation performance. During ballistic testing, current combat helmet test protocols use clay to record the helmet backface deformation signature, which is used as an important criterion to measure the helmet effectiveness at preventing head injury. However, according to a …

A critical investigation of the use of infrared thermography in determining the condition of composite materials
… laminates were subject to modified Charpy and ballistic testing to create barely visible impact damage (BVID). The damaged parts were then subjected to inspection using techniques such as pulsed thermography, thermoelastic stress analysis (TSA), immersion ultrasonic testing, microscopy and …
