shock wave In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a me ...

s on materials, dynamic behavior of materials, and materials in extremes. Originally formed in 1984 as the Topical Group on the Shock Compression of Condensed Matter, the group has sponsored the Biennial International Conference on Shock Compression of Condensed Matter (SCCM) and awards the George E. Duvall Shock Compression Science Award. The Topical Group changed to its current name in 2023 to reflect a broader community including static high compression experiments. While specific topics and session names are set for each Biennial SCCM Conference, frequent topics include: *

Detonation Detonation () is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations propagate supersonically through shock waves with ...
