A constitutive model for the shock Hugoniot of porous materials in the incomplete compaction regime

Abstract

A constitutive model is developed for the shock Hugoniot of porous materials in the incomplete compaction regime. The model is based on a comparison between the shock compaction and quasi-isostatic compaction and utilizes empirical data of material strength and compaction characteristics. The model requires only well-documented material constants as inputs. It accurately predicts porous Hugoniots for a wide range of materials.
