The use of high-modulus ceramic materials under conditions simulating the screen protection space objects from damage by fragments man-made debris is considered. introduction an aluminum jet at a speed ~10 km/s into barrier located behind brittle material screens was experimentally studied. A comparative analysis parameters residual cavity in made it possible to reveal effect structural rearran...

Abstract Background The strength of cotton fiber has been extensively studied and significantly improved through selective breeding, but elongation largely ignored, even though contributes to determining the energy needed break fibers. Recent developments calibrate high volume instrument (HVI) for renewed interest in elongation. However, it is not understood how best utilize yet another propert...

During the high velocity impact of an object on a solid covered with thin fluid layer, lubricated contact exists within short time in which liquid is squeezed out from contact. This important for e.g. grip shoes wet surfaces. We experimentally study squeeze flow such layers and find that amount viscous dissipation determines how much remains after kinetic energy impacting absorbed. For impacts ...
