摘要: 本文根据Mie-Gruneisen状态方程,以Hugoniot压强和能量作为参考压强和能量,在稀疏区利用实验的断裂强度和结合能,给出了一种简单实用的弹塑性流体状态方程,并提供了稀疏区的Gruneisen系数表达式。Abstract: This paper presents a convenient and practical EOS of elastic-plastic fluid, based on the Mie-Gruneisen equation, using Hugoniot pressure and energy as the reference with density 0. In addition, the relation of Gruneisen coefficient (p)for 0 is also presented. The practicality and reliability of these formulas have been verified in actual works.
