Shock-wave equation of state of rhyolite

Shock-wave equation of state of rhyolite

We have obtained new shock-wave equation of state (EOS) and release adiabat data for rhyolite. These data are combined with those of Swegle (1989, 1990) to give an experimental Hugoniot which is described by Us=2.53(±0.08)+3.393(±0.37)up for up<0.48 km s−1 , Us=3.85(±0.05)+0.65(±0.03)up for 0.48≤up<2.29 km s−1 , Us=1.52(±0.08)+1.67(±0.02)up for 2.29≤up<4.37 km s−1 , and Us=3.40(±034)+ 1.24(±0.0...

Periodic Wave Shock solutions of Burgers equations

In this paper we investigate the exact peroidic wave shock solutions of the Burgers equations. Our purpose is to describe the asymptotic behavior of the solution in the cauchy problem for viscid equation with small parametr ε and to discuss in particular the case of periodic wave shock. We show that the solution of this problem approaches the shock type solution for the cauchy problem of the in...

Modified Equation of Shock Wave Parameters

Among the various blast load equations, the Kingery-Bulmash equation is applicable to both a free-air burst and a surface burst that enables calculations of the parameters of a pressure-time history curve. On the other hand, this equation is quite complicated. This paper proposes a modified equation that may replace the conventional Kingery-Bulmash equation. The proposed modified equation, whic...

Equation of State for Mercury

An analytical equation of state by Song and Mason is developed to calculate the PVT properties ofmercury. The equation of state is based on the statistical-mechanical perturbation theory of hard convexbodies and can be written as a fifth-order polynomial in the density. There exists three temperaturedependentparameters in the equation of state; the second virial coefficient, an effective molecu...
