Hugoniot shock
WebWhen highly porous materials are subjected to shock compression, a large amount of heat is generated during the compression. If the material is porous enough and the shock intensity is high enough, abnormal Hugoniot behavior is observed because the material expands due to the heating.1-6 This anomaly manifests WebAs implied before, the shock Hugoniot curve must pass through A. For different values of q, one obtains a whole family of Hugoniot curves. [Pg.271] When q = 0, the Hugoniot curve represents an adiabatic shock. Point 1 (Pi, p ) is then on the curve and Y and J are 1. Then [ (l/pt) - (Ilp2) = 0, and the classical result of the shock theory is ...
