- Title
Study of defects in quartz glass with the action of high-velocity microparticles on port-holes.

- Abstract
The operation of any space craft involves a danger of random collisions with so-called space junk and bombardment by different microparticles (meteorites). Traces of impacts of microparticles of meteorites in the form of damage defects on the surface of the quartz glass of port-holes have been found on the MIR space station and International Space Station (ISS). Research to find criteria to assess the residual strength of quartz glass is being conducted to assess the danger of these defects. Five subzones of damage have been found in the zone of a defect. Analysis of these subzones shows that the dangerous subzones-stress concentrators-are the 3rd and 4th subzones. A method has been found for evaluating the impact energy of microparticles according to the morphology of defects. The impact energy has been determined for a defect with diameters 2.5 mm, obtained on the No. 13 port-hole of the ISS.
