Popis: A Gruneisen equation of state (EOS) is developed for the polymer TPX (poly 4-methyl-1-pentene) within the LANL hydrocode FLAG. Experimental shock Hugoniot data for TPX is fit to a form of the Gruneisen EOS, and the necessary parameters for implementing the TPX EOS in FLAG are presented. The TPX EOS is further validated through one-dimensional simulations of recent double-shock experiments, and a comparison is made between the new Gruneisen EOS for TPX and the EOS representation for TPX used in the LANL Common Model.
