An Examination of the JWL Equation of State

Abstract

The JWL equation of state, ubiquitous in the field of explosive metal interactions, is examined from the perspective of thermodynamic foundation and compatibility. Because there is no founding document for the JWL equation of state, there exist different interpretations of the equation, which is the source of substantial confusion. In starting with a general entropy-based equation, we show what assumptions are necessary to simplify the equation of state to the JWL equation forms commonly found in the literature.
