1. 1. On focusing of strong shock waves

   Författare :Veronica Eliasson; Nicholas Apazidis; Nils-Erik Molin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shock focusing; imploding shock; converging shock; reflected shock; annular shock tube; Fluid mechanics; Strömningsmekanik;

   Sammanfattning : Focusing of strong shock waves in a gas-filled thin test section with various forms of the reflector boundary is investigated. The test section is mounted at the end of the horizontal co-axial shock tube. Two different methods to produce shock waves of various forms are implemented. LÄS MER

3. 2. On focusing of shock waves

   Författare :Veronica Eliasson; Nicholas Apazidis; John Dear; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; converging shock; Euler equations; imploding shock; Mach reflection; regular reflection; shock focusing; shock tube; Fluid mechanics; Strömningsmekanik;

   Sammanfattning : Both experimental and numerical investigations of converging shock waves have been performed. In the experiments, a shock tube was used to create and study converging shock waves of various geometrical shapes. Two methods were used to create polygonally shaped shocks. LÄS MER

5. 4. Terrestrial consequences of hypervelocity impact – shock metamorphism, shock barometry, and newly discovered impact structures

   Författare :Sanna Alwmark; Berggrundsgeologi; []
   Nyckelord :Impact cratering; Impact structure; Shock metamorphism; Shock barometry; Quartz; Planar deformation features; Siljan; Målingen; Hummeln;

   Sammanfattning : Impact cratering was once considered a rare geological process of no, or little, importance to the evolution of the Solar System and planet Earth. After more than 50 years of space exploration and the discovery of numerous (~190 as of October 2016) impact structures on Earth, this view has changed, and it is now clear that impact craters are in fact one of the most common morphological features on solid bodies in the Solar System.
